2-WAY NORMALLY OPEN Valve
PeterPaul explosion proof valves are used where fire or explosion hazards exist due to the presence of flammable gases or vapors, flammable liquids, combustible dust, or easily ignitable fibers. Hazardous Location valves are recommended, or in some cases compulsory, where a high level of protection from explosion is required.
- Miniature Hazardous Location valves using even less power than an E51.
- Flame-Proof construction.
- High quality engineering.
| MAX. OPER. PRESS. DIFF. | ORIFICE SIZE | CV FACTOR | VALVE NUMBER | |
|---|---|---|---|---|
| AC | DC | |||
| 200 | 200 | 1/32 | .020 | EL51G8XCCM-∆ |
| 120 | 120 | 3/64 | .048 | EL51H8XCCM-∆ |
| 50 | 50 | 1/16 | .075 | EL51J8XCCM-∆ |
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 (EL51H8XCCM 120/60) repair pack (5KEL51H 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 (OEL51HDDCCM 120/60)

PeterPaul has created this page for you so you can calculate the flow or Cv (flow coefficient) to make the relationship visible between the pressure drop (the difference in pressure between two points of a liquid/gas carrying network) and the flow rate.
The use of this flow coefficient (Cv) calculator offers a standard calculation to compare valve capacities and sizing for a wide range of applications. The type and sizing of a valve or regulator can have a large impact on the performance of the assembly for transferring gas or liquids in the system.
