The pin is located outside the valve and is the heart of the operation, acting as the sensor and actuator. Once buckled, one person in under a minute can reset the pin in place without breaking the line.
The Model DG valve provides safety for a variety of pressure relief applications including but not limited to: Oil and Gas Production, Pipeline, Well Drilling, Chemical Processing, Food Processing, Waste Water Processing, Pharmaceutical Processing, Pulp and Paper Plants, and anywhere that conventional relief valves and rupture discs are used.
