Reducing valves
41-23, Direct acting - Large capacity
The Type 41-23 Steam Pressure Reducing Valve regulates the steam pressure downstream from the valve to a pre-adjusted set point value.
Features & Benefits
- Extremely robust
- Easy to adjust
- Easy to maintain
DRV7, Direct acting - Large capacity
The downstream steam pressure signal moves the diaphragm against an adjustable spring. The valve movement is proportional to sensed pressure, but the greater the flow, the larger the offset.
Features & Benefits
- Extremely robust
- Easy to adjust
- Easy to maintain
- Can also be used as a surplussing valve
DP27, Pilot operated - Medium capacity
The downstream steam pressure signal operates a pilot valve against an adjustable spring, which changes the flow to the main diaphragm. This modulates the main valve adjusting the flow to maintain the desired downstream pressure. There is virtually no offset between full and no load conditions.
Features & Benefits
- Extremely accurate
- Easy to adjust
- Multi-pressure types
- On/off capability
- Can also be used as a surplussing valve
BRV2,LRV2 & SRV2, Direct acting - Low capacity
The downstream pressure signal moves a set of bellows against an adjustable spring. Valve movement is proportional to downstream pressure. The greater the flow, the larger the offset.
BRV2 - For normal steam applications
SRV2 - For clean steam applications
LRV2 - For liquids
Features & Benefits
- Extremely robust
- Easy to adjust
- Easy to maintain
