The Dresser Style 175 gas service valve uses two complementary sealing principles that work together for positive shutoff at all rated working pressures to 175 psi. The oil-tempered steel spring exerts a constant force on the tapered plug and seal inserts, providing a seal against low line pressure. At higher pressures, this spring load is supplemented through a unique design that employs line pressure to exert an additional positive sealing force. As line pressure is increased, greater sealing force on the elastomeric seals is produced, causing the valve to remain gas tight at all pressures within its recommended working range.

Tamper-Proof per DOT Specifications
The Style 175 valve is assembled at the factory and sealed against tampering by a spring-loaded stainless steel retaining ring that cannot be removed with ordinary tools. It is tamper proof as specified in DOT 192.363 Part C.

Low Operating Torque
A TFE coated retaining ring, plus permanently lubricated port seals, help ensure low, uniform operating torque, preventing the plug from freezing to the body.

100% Factory Tested
Each valved is tested at high and low pressure while in a clear, non-corrosive fluid.
