Our changeover valve is a three-way globe valve that is designed for use in all locations that a shutdown cannot be achieved, whether that be due to safety concerns, or because of production conditions. With a globe valve style design the product has the advantage over conventional three-way ball or plug valves.
Changeover valves used with two associated pressure relief devices will provide continuous overpressure protection to a process or protected system. They enable a swift and safe switch between products, safety systems or to start-up tanks when used a diverter valve. Changeover valves allow pressurized systems to have dual safety relief devices, letting relief devices get their maintenance without interrupting protection from overpressure.
1” x 2” to 20”
Superior flow behaviors and a low pressure loss verified by using 3D flow simulations.
Optimization of the body interior and the trim parts
Optimization of the deflection angle < 30°
Compact height allows for a short pipe feed to the safety relief valve
Elimination of sharp passages that might cause flow disruption
