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,...

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

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...

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. Adjustable, stainless steel metering adapters shown mounted on...

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...

EPDM Seals

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...

Peter Paul Develops New FKM Seals for Gasoline and Propane Valve Applications

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...

Swell Resistent Printers Gum

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...

Cryogenic Valves For Low Temperature Applications

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...

Making Kalrez® Seals Affordable for Volume Valve Applications

Kalrez ® Perfluoroelastomer seals, a product of DuPont Dow Elastomers, are impervious to more than 1,600 chemicals and solvents, inert to most chemically induced swelling, useful in temperatures from –20°F to 600°F, and last much longer then other elastomer seals. Unfortunately, at about $2,000 per...

3-Way and 2-Way Solenoid Valves For Quiet (No-Click) Operation

Peter Paul Electronics Co., Inc. has recently developed solenoid valves for use in medical applications such as hospital beds, breathing apparatus, and inflatable mattresses for burn patients in which a bumper is installed for quiet operation. Typical Peter Paul Electronics 3-way and 2-way solenoid...

Peter Paul EPDM seals, non-absorbent, high pressure uses

New Britain – Peter Paul now produces Ethylene Propylene Diene Monomer (EPDM) valve seals for high pressure gas applications in place of more absorbent standard rubber seals. EPDM seals can be applied in medical environments, aerospace projects, and similar uses where gas absorption can interfere...

Stacking Valve Tie Rod Bodies Allow the Creation of Modular Manifold Valves

Standard, conventional, one-piece machined stainless steel, brass, or aluminum solenoid valve manifolds allow the economical, low profile grouping of valves in compact arrays. Like any other purpose-designed, machined component, these manifold valves are perfect for fixed, continuous operations...
