What's New - Special Applications

New High Pressure, Economical Series 20 Valve

New Britain, CT Peter Paul now offers high pressure Series 20 Models H21 & H24 valves with a redesigned guide pin that provides high seal ability at lower cost. Standard operating pressures are to 2,000 psi (H21) and 1,000 psi (H24), in gas or liquid. Higher-pressure ratings are also available (consult factory). Special sealing in plastic, Delrin^® or steel is available.

Model H21 is a 2-Way Normally Open valve with an orifice size of .6mm and a CV factor of 0.10. Burst pressure is to 5,000 psi. Standard operating temperature is from 0ûF (-18°C) to 104°F (40°C). Model H24 is a 3-Way Normally Open valve with an orifice size of .6mm 1/32" and a CV factor of 0.10 inlet; .024 exhaust. Standard operating temperature is from 0°F (-18°C) to 104°F (40°C). Coils in both valves are DC operated.

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.

Metering Adapter Adds To Utility Of Our Series 20 and 30 Solenoid Valves

A new, adjustable, stainless steel metered adapter for Series 20 and 30, 2-way N.O. and 3-way solenoid valves provides a manually adjustable flow control to a valve which creates a speed control for the process the valve is controlling.

While our solenoid valves can be configured with metering in the valve bodies, the use of metering in the sleeve port adapter on either the top inlet or exhaust allows the user to set the best possible flow parameters for the specific applications. For instance, to restrict the return speed of a cylinder, the metering adapter acts as a damper on the process. With the use of these adapters, it is also possible to pipe the exhaust from the solenoid valve out of the area rather then exhausting directly to atmosphere. The metering adapters are available for either 1/8 NPT or ¼ NPT porting and are used for liquid and gaseous media.

The metering adapter is typically used as a metered exhaust for 3-way normally open valves, or as a metered normally open port in multi-purpose or directional control valves.

The 55-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.

Peter Paul Electronics provides a number of solenoid valve and manifold combinations for the refigerant recovery / recycle equipment market, including Series 50 valves and Series 20 (center and lower right) valves, plus stainless steel, brass, and aluminum manifolds. The built-in Peter Paul back pressure design on some models eliminates redundant check valves by stopping possible refrigerant leakage to atmosphere during HVACR system servicing.

Line of Solenoid Valves and Manifolds for CFC Recovery Systems Announced By Peter Paul

Background:

The Environmental Protection Agency is now beginning seriously to enforce the provisions of the Clean Air Act involving recovery and recycling of chlorofluorocarbons (CFC's) used as the refrigerants in air conditioning systems, auto air conditioners, and refrigerators. The manufacture of these CFC's will be totally banned at the end of 1995 because of the threat they pose to the Earth's ozone layer which blocks the sun's harmful ultraviolet rays.

After May 25, 1993, any technician opening up a charged system without using a certified refrigerant recovery or recycling unit will be in violation of the Clean Air Act. After July 23, 1993, anyone repairing air conditioning and refrigeration systems without having self-certified to the EPA that recovery and recycling devices are being used will also be in violation of the Clean Air Act.

In fact, all technicians working in this field will have to be trained and certified and will be required to use EPA certified refrigerant refilling and capture equipment. In addition, it will be unlawful for anyone to sell or distribute small containers of refrigerant except to a certified HVACR technician to discourage do-it-yourself repairs on auto and home air conditioners.

Just as virtually every auto repair station and dealership has or will eventually have an exhaust emission analyzer so that automobiles will meet mandatory emissions standards, every technician who goes up on a rooftop to service an air conditioner or who charges up vehicular air conditioners will be required to use a portable CFC capture and/or recycle system certified to federal standards. As long as CFC-based coolants are in use, probably for the rest of this century, the market for EPA-mandated refrigerant recovery/recycling equipment will continue to grow.

To meet the needs of the approximately 50 current manufacturers producing portable refrigerant recovery/recycling systems, Peter Paul Electronics Co., Inc., New Britain, Connecticut, has created a family of 2-way and 3-Way, normally open and closed low power consumption solenoid valves with inlet pressure ratings up to 500 psi and complementary manifolds to serve these requirements. Equipped with 1/8 and 1/4 NPT pipe 3/8'" ports, 1/4" copper (sweat) tubing, or provision for manifold mounting, these easy-to-install valves are available with spade terminals, lead wires, or conduit connection for any standard AC or DC voltage application. Orifice sizes range from 1/32" to 1/4", and special Neoprene^R seals are incorporated for CFC applications. Compact manifolds of stainless steel, brass, or aluminum with up to eight inlet ports standard help to cover the variety of CFC recycling system designs.

The 45-year-old Peter Paul E1ectronlcs provides, through distributors worldwide, a broad range of standard and 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 applications; and a vast array of body, housing, and coil options for specialty valve construction. Most Peter Paul solenoid valves are UL and CSA listed.

Peter Paul Media Isolation valves employ nylon valve bodies and custom porting to keep corrosive liquid media isolated from the valve operator in medical, instrumentation, chemical, food processing, and similar applications.

Peter Paul Announces Media Isolation Valves for Continous and Intermittent Duty

A compact, Series 50 Solenoid Valve utilizing a molded nylon body and a diaphragm which isolates potentially corrosive media from the valve operator parts compatible with nitrile (Buna N), silicone, EPDM, and other available elastomers is now offered by Peter Paul Electronics, New Britain, Connecticut, for applications in the medical, instrumentation, chemical, and food processing industries.

This 2-way Normally Closed valve was specifically designed for a customer who had been using a competitor's valve and was experiencing a relatively high reject rate in the field. Working closely with this customer, Peter Paul developed a valve and supplied prototypes which led to production orders. So successful was the Peter Paul design that rejects became nonexistent.

At the present time this valve is available with a 3/64" orifice (0.037 Cv),l/8" NPT female (side) inlet port, and 1/8" NPT male (bottom) outlet port. Rated at 50 psi maximum inlet pressure with a 5 psi maximum back pressure, it provides power of 4.25 watts A.C./7.25 watts D.C. Standard coil voltages are available with 1/4" spade terminal coils.

The back pressure limitation can be eliminated by reducing the inlet pressure to 35 psi and using an intermittent duty coil, power rated at 17 watts D.C. to provide a duty cycle of 0.167 minutes ON maximum and 0.833 minutes OFF. Other orifice sizes can be made available (consult factory).

The 45-year-old Peter Paul E1ectronlcs provides, through distributors worldwide, a broad range of standard and 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 applications; and a vast array of body, housing, and coil options for specialty valve construction. Most Peter Paul solenoid valves are UL and CSA listed.
