P40 & P40 NACE Compliant Natural Gas and Propane Regulators
The General Purpose P40 and P40 NACE Natural Gas and Propane Regulators are reliable precision units designed for instrumentation and general purpose use in both standard (P40), and corrosive environments (P40 NACE). The P40 NACE complies with NACE material requirement MR0175 for sulfide stress cracking resistant metallic material for oil field equipment. These regulators are generally superior in regulated pressure vs. flow, forward-to-reverse flow offset, supply pressure sensitivity, repeatability and stability.
Features:- Superior regulation characteristics
- Rugged, corrosion-resistant construction
- Economical
- Self-relieving
- Standard tapped vent
- Excellent stability and repeatability
- Soft relief seat on P40
- Several mounting options
- Instrumentation and general purpose use in both standard (P40), and corrosive environments (P40 NACE).
