Non-Boiler Steam and Vapor Service Safety Relief Valve
Dresser Consolidated provides the right valves by offering a full range of reliable, high-performance valves for energy and power applications. The Dresser Consolidated 1900/P steam internal series is designed for economizer and organic vapor service. It delivers smooth performance with reliable seat tightness even in difficult applications. And it offers a low cost of ownership.
The 1900/P Series includes exclusive Thermodisc® technology which compensates for temperature gradients around the seating surface. This creates a higher degree of seat tightness and a low spindle bearing point to assure proper alignment and load distribution at the seating surface. The design also prevents the disc from sliding across the seat while it is actuating. Plus, a single blowdown ring makes it possible to set and test a valve that has been in service.
