New Magnetic Latching Valve in a Small Package

Peter Paul introduces its low-cost, magnetic latching valve in a small package with pressures to 500 psi, for use where power is limited or coil heating is undesirable. This small, economical package can be used in tight spaces and remote areas where continuous power may not be available, or in battery-powered portable equipment. It also has uses in medical and chemical analyzers where continuous application of power causes unwanted coil heat.

The new valve is offered in 6-60 Volts DC and draws approximately 7 Watts when energized. A coil and rare earth magnet assembly, encapsulated into a single package is offered with either a lead wire or Male DIN style connection. The 2 WNC valve package with leads is only 2.50 " (63.5 mm) H x .1.13" (28.6 mm) W. The unit requires only 30 milliseconds of power application to latch or unlatch. When latching, the magnetic polarity of the coil and magnet form a strong pull on the valve plunger, which moves it to the energized position. It is kept there through the strength of the magnet alone. To unlatch, the field of the DC coil voltage is briefly reversed.

Peter Paul Electronics, established in 1947, provides through worldwide distribution a broad range of standard and miniature solenoid valves, explosion proof, high-flow and high pressure models - most UL and CSA listed; complementary manifolds and stacking bodies in stainless, brass or aluminum; solenoid valve operators for OEM use; and a vast array of body, housing and coil options for standard and special applications.

Peter Paul Launches Low-power Magnetic Latching Valve

NEW BRITAIN, CT-- Peter Paul Electronics Co., Inc., now offers a low-cost, magnetic latching valve for use where power is limited or coil heating is undesirable.

The latching component is external to the valve for adaptation to any Series 20, 30 or Series 80 valve with an internal spring change. The valve can be used in remote areas where continuous power may not be available, or in battery-powered portable equipment. It also has uses in medical and chemical analyzers where continuous application of power causes unwanted coil heat.

The new valve will initially be released in 6, 12, 24, and 28 volts DC, each drawing only 10W when energized. Other voltages will be available upon request with minimum order requirements. The valve consists of a coil/magnet assembly encapsulated into a single package with an integral Form “A” DIN connection. It requires only 50 milliseconds of power application to latch or unlatch.

When latching, the magnetic polarity of both coils and ring magnet form a strong pull on the valve plunger which moves it to the energized position. It is kept there through the strength of the magnet alone. To unlatch, the field of the DC coil voltage is briefly reversed.

Peter Paul Electronics, established in 1947, provides through worldwide distribution a broad range of standard and miniature solenoid valves, explosion proof, high-flow and high pressure models - most UL and CSA listed; complementary manifolds and stacking bodies in stainless, brass or aluminum; solenoid valve operators for OEM use; and a vast array of body, housing and coil options for standard and special applications.

Series 50 Explosion-Proof solenoid valves with molded coils for hazardous locations are offered with added protection from moisture in the form of new O-ring and flat gasket flurocarbon elastomer seals and an RTV conduit seal.

In this heat treat application, a Peter Paul Series 20, 2-way. normally closed, conduit valve controls the air supply for a small, conveyorized heat treat oven at Accurate Brazing Co.

Peter Paul High-Heat Solenoid Valves Developed

A new line of high-heat solenoid valves and valve operators has been developed by Peter Paul Electronics Co., Inc., New Britain, Connecticut, to meet growing applications typically involving high temperature fluids.

The majority of solenoid valve applications fall within IEEE Class A temperature limits on coil construction. These coils are limited to a total temperature of 105°C. This maximum temperature rating represents the combination of ambient temperature and temperature rise from coil input power with higher wattage coils producing more heat. In addition, media temperature must not raise total temperature beyond the maximum to stay within the class limit. The material construction of the valve and coil, including magnet wire, splicing tape, lead wire insulation, epoxy and other components now have been modified to allow Peter Paul solenoid valves to be rated for higher temperatures than Class A, based on application.

Specifically, Peter Paul has produced a new series of Class "H" high-heat valves with a maximum limit of 180°C for use in industrial applications such as heat treating, where the ambient temperature is likely to be considerably higher than the standard 25°C working environment, requiring the much higher heat limit of Class "H."

The 45-year-old Peter Paul Electronics, through a world-wide distributor network, provides a broad range of Standard, Miniature solenoid valves; Explosion-Proof, High-Flow, and High Pressure models; complimentary manifolds and stacking bodies in stainless, brass, or aluminum; solenoid valve operators for OEM use; and a vast array of body, housing, and coil options for standard and special applications. Most Peter Paul solenoid valves are UL recognized and CSA listed.

Dual voltage, four wire coil and completed dual voltage solenoid valve (Series 20, left and Series 50, right) are used when two voltages may be involved in a process, typically 120/240 VAC or 240/480 VAC.

Don’t Forget Our Dual Voltage Solenoid Valve Coils

For many small AC motor applications including powered hand tools, it has become quite common for the motors to be configured to operate at one of two voltage levels, typically 120/240 VAC-60 Hz or 240/480 VAC-60 Hz.

Now, for the Series 20, 50 60 and 80, 2 and 3 Way solenoid valves, we can provide dual voltage coils to allow the solenoid valves to be wired for either of the applicable voltages, reducing parts inventory and product installation / assembly at the distributor, OEM and end user locations.

For specific applications in which more than one voltage might be encountered, the dual voltage solenoid valves are identical to their single – voltage versions except for the additional coil windings and leads.

Peter Paul Series 80 Solenoid operated diaphragm valves with internal pilot may now be specified with a solid state timer for applications such as draining condensation in compressed air systems. The timer features power/operation status lights, pushbutton manual override, and adjustable off time of 1-45 minutes and on time of 0.25-25.0 seconds.

Solid State Timer Adder to Large Orifice Peter Paul Solenoid Valves

For applications such as draining condensation in compressed air systems, Peter Paul Electronics Co., Inc., New Britain, Connecticut, has added a solid state timer accessory to the Series 80 group of 5/8" iameter orifice, solenoid operated, 2-way, normally closed diaphragm valves. The integrated timer and valve combination is used for many on/off cycle applications.

In operation, the off-cycle is initiated with the application of power to the valve's input terminals. At the end of the pre-set off time, the solenoid is energized and the on-cycle begins. At the conclusion of the pre-set on time, power is removed from the solenoid and a new cycle begins; this cycling continues until the power is removed from the valve's input terminals.

The solid state timer provides 1-45 minute adjustable off time and 0.25 sec. to 25.0 sec. adjustable on time with pushbutton manual override and status lights to indicate power and operation. Pressures of 5-150 psi through 1/2 NPT portings; voltages of 120/60, 110/50, and 240 VAC; and 9.5 watts normal power consumption are standard.

The Series 80 valve with timer is a 2-3/4" x 6" x 3-17/64" package in which the timer and coil may be rotated 360° for installation convenience. The timer may also incorporate DIN male connector for wiring directly into a system.

The 55-year-old Peter Paul Electronics Co., through a worldwide distributor network, provides a broad range of standard and miniature solenoid valves; Explosion-Proof, High-Flow, and High Pressure models; complimentary manifolds and stacking valves in stainless, brass, or aluminum; solenoid valve operators for OEM use; and a vast array of body, housing, and coil options for standard and special applications.

Encapsulated Diode Spade Coil For Series 15 Solenoid Valves Announced By Peter Paul

A full wave bridge can now be encapsulated into the coil assembly of Peter Paul Series 15 solenoid valves, according to Peter Paul Electronics Co., Inc., New Britain, Connecticut. By embedding the required electronics in the coil, a DC valve can be driven by common AC voltages.

Each valve's encapsulated coil contains a diode circuit that converts common 50/60 Hz voltage to DC. Running the coil on DC eliminates the in-rush current associated with AC valves, thus limiting the excessive heat build-up encountered with frequently cycled valves. The use of DC coil voltage also allows the use of an elastomeric damper within the valve itself. This damper reduces the audible click, which occurs on actuation as well as increases the life of the valve, for a wide range of hospital and laboratory applications.
