High capacity, two ring control, full nozzle safety valve for saturated and superheated steam service.
The Crosby Style HL Safety Valve is a high capacity, flanged steel safety valve specifically designed in accordance with ASME Section I and Section VIII.
Features & Benefits:
- The guide is held in place using the method employed by all the leading high-pressure safety valve manufacturers, thus eliminating the age-old industry problem of the guide-to-body threads corroding in service, which can require major repairs.
- The HL valve has a full nozzle that threads into the body, making it easy to remove and less expensive to repair should it be damaged in service. The full nozzle is designed with spanner wrench slots for easy removal and installation.
- An external blowdown adjustment makes final minor blowdown adjustments in the field very easy and minimizes the testing time.
- The HL’s Flexi-Disc®, which is more common in high pressure safety valves, offers improved seat tightness.
- The special designed cover and overlap collar form a unique back pressure chamber for improved blowdown and prevents steam from heating the spring, which might affect set pressure.
- The built-in mechanical lift stop prevents overlift and ensures stability during the relieving cycle.
