Pipe Rupture Valve (PRV)


Mounted directly onto the main jack connection, the Pipe Rupture Valve (PRV) is simple to adjust and extremely reliable in operation. Should an overspeed of the elevator occur, the damped closing of the PRV ensures a quick but smooth slowdown of the car. Slowing to a stop is standard; slowing to a down creep speed is optional.
Grooved or NPT straight through line connections enable the customer to attach the PRV to the existing cylinder and pressure line connections in the shortest possible installation time.
