Series 2700 Pressure Relief Valves
 |
Superior Design
- A single design handles air, steam, vapor and liquid services.
- Maximum interchangeability of parts affords easy maintenance and lower costs.
- Fixed blowdown design simplifies testing and repair. Maximum blowdown of 5% to 15% regardless of service.1
- A built-in lift stop ensures stable performance.
- Balanced design in “C” and “D” orifices nullifies the effects of back pressure on set point.
ASME Code Certification
- Manufactured in conformance to Section VIII of the ASME Boiler and Pressure Vessel Code for air, steam, and liquid service.
- Capacities certified by The National Board of Boiler and Pressure Vessel Inspectors.
Optional O-Ring Seat Design
- O-ring seat design available for maximum seat tightness.
- Teflon® available at higher pressures to provide the same zero bubbles per minute leakage as elastomer O-ring seats.
