REGULATORS
P32 Superior regulation and excellent stability make the P32 Regulator ideal for lower flow applications.
Square head adjustment screw allows for easy in-field calibration. The P32 is available with handwheel adjustment,
output
pressure gauge and/or mounting bracket as options.The use of a relief valve is recommended for
this product in accordance with NFPA 58.
FEATURES BENEFITS
60-mesh screen Harmful particles blocked
UL listed (Standard P32) Non-Relieving
NACE construction available
P36 This reliable precision preset regulator is ordered with the exact pressure regulation required. Ideal
for areas requiring tamper resistant components or where incidental re-adjustment is a concern. The use of a
relief valve is recommended for this product in accordance with NFPA 58.
FEATURES BENEFITS
60-mesh screen Harmful particles blocked
Dripwell option Release undesirable moisture
UL listed (Standard P36) Non-Relieving
NACE construction available
P37 The P37 contains many of the same characteristics as the P38, but at a reduced price. At 110
SCFM (16.5 Mbtu/hr), the P37 offers flow rates comparable to current market suppliers. The use of a relief
valve is recommended for this product in accordance with NFPA 58.
FEATURES BENEFITS
Balanced pintle design High flow capacity
Bubble tight/non-relieving Enclosed space use
16.5 Mbtu/hr. (110 scfm) High volume applications
UL listed Non-Relieving
Bellofram Rolling Diaphragm
P38 The P38 uses a patented balanced pintle design which eliminates unsteady changes in outlet
pressure due to inlet pressure fluctuations. The P38 is a spring opposed, diaphragm - operated, non-relieving
regulator. The use of a relief valve is recommended for this product in accordance with NFPA 58.
FEATURES BENEFITS
Balanced pintle design Exceptional flow capacity
Bubble tight/non-relieving Enclosed space use
27 Mbtu/hr (260 scfm) High volume applications
UL listed Minimal effect on output pressure from variation
