Peter Paul Electronics Co., Inc. manufactures an extensive line of solenoid operators and valves for original equipment manufacturers who serve the medical industry. Some of the Peter Paul valves adapted by these manufacturers appear above, with a brief description below of their applications. Peter Paul also manufactures a complete line of standard and explosion-proof solenoid [...]
These are some typical 2-way and 3-way normally open and closed low power solenoid valves that are intended for portable refrigerant recovery-recycling systems. Their inlet pressure ratings range up to 500 psi. They come equipped with 1/8″ and 1/4″ NPT pipe ports, 3/8″ copper sweat tubing, or with provisions for manifold mounting. Spade terminals, lead [...]
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 [...]
Background: 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 [...]
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. Adjustable, stainless steel metering adapters shown mounted on our (left to right) Series 30 grommet 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 [...]
Special EPDM (Ethylene Propylene Diene Monomers) solenoid valve seals are used for applications where high-pressure gases tend to be absorbed in standard rubber seals. Solenoid valve plunger travel stroke is typically 0.020 to 0.050 in., depending on orifice size. Choosing the wrong seal material could literally shut off the valve flow. Notice the swelling in [...]
Today’s alternative powered vehicles and reformulated gasoline’s are causing increased occurrences of solenoid valve seal swelling and cracking in service. This has created the need to reformulate existing FKM compounds to maximize their properties in reformulated gasoline’s, which have significant amounts of MTBE and alcohol. Only a small amount of swell can shut off valve [...]
Another thing we’ve done is a special elastomer for use with water-based printing links. We think of ink as being almost benign, but sometimes it can be rather aggressive to certain materials, and swelling of the rubber typically causes a big problem in the dispensing valves for ink. Peter Paul has worked with our existing [...]
Our solenoid valves, those precision electro-mechanical “switches” required to perform millions of unattended cycles in applications ranging from coffee vending machines to metal cutting machine tools, are also widely employed at low temperatures to about –40°C involving gaseous and liquid refrigerants and liquid nitrogen. We can provide a wide variety of cryogenic valves and manifolds, [...]
