Peter Paul Hazardous Location Valve Model E21
PeterPaul single orifice valves feature a closed orifice in the energized position, preventing any flow between the inlet and outlet ports. Additionally, PeterPaul explosion-proof valves are designed for environments with fire or explosion hazards due to the presence of flammable gases, vapors, liquids, combustible dust, or easily ignitable fibers. These hazardous location valves are either recommended or mandatory where a high level of explosion protection is required.
- Explosion Proof
- The flagship valve initially created for fluid power industry.
- Heavy duty and made of stainless steel.
- A real workhorse with proven performance.
- It has the greatest amount of options available of all the valves.
- Wide range of orifice sizes from 1/32″ to 1/8″
Available on backorder
^ VALVES WITH 1/8 ORIFICE ARE NOT UL OR CSA LISTED
* FKM seals not recommended for pressure ratings above 500 PSI
+ Ratings in brackets are optional extended ratings; consult factory.
Ordering Information:
Seal Material: Replace ∆ with desired code – Blank = Nitrile (Buna) S = Low Temp Buna. N = FKM* E = Neoprene A = EPDM
When ordering valves or repair packs add voltage and frequency to complete valve number. for examples: valve (E21K9ZCCM 120/60) repair pack (2KE21K AC)
When ordering operators add the letter “O” to the front of the valve number, replace body port number with the letter “D”: example: operator (OE21KDDCCM 120/60)
Operating Conditions:
- Media: Air, water, and other fluids compatible with standard Buna seals. Hot water, steam gasoline, and many oils require special seal materials. (Series 20 pressure ratings may change due to the viscosity of the liquid.)*
- Valve Temperature Range:
- Standard Valves – 0°F (-18°C) to 104°F (40°C) ambient; 0°F (-18°C) to 150°F (65°C) media.
- Optional Valves – can tolerate much higher or much lower ambient and media temperatures.*
- Maximum Operating Pressure Differentials: See table above.
- Burst Pressure: 5000 PSI
- Leakage: Bubble tight for standard valves.
- Vacuum: To 5 Microns*
