Description
Groth 1400 Series pilot-operated relief valves are used to replace weight-loaded or spring-loaded valves in many applications, with the goal of increasing efficiency and reducing evaporation losses. These valves offer several advantages compared to traditional valves. For example, process pressures can be closer to the set pressure than would be considered prudent and safe with a traditional valve. In addition, greater conservation is achieved due to minimal product loss, which in turn generates increased profits.
The Model 1460 is similar to the 1420, but without a vacuum breaker.
Easy, precise adjustments
Only the pilot needs to be adjusted
Lower profile and weight than spring-operated models for high settings
Remote pilot sensing option, allowing it to sense the actual system pressure
Remote or manual blowdown available
The main valve remains closed until set pressure is reached
Full opening at 10% overpressure
Modulating action that conserves product
Soft seat that creates a tight seal to conserve product and minimize valve wear
Top entry that allows valve maintenance without removing it from the mounting
