Piston valve MTW series

electrically-actuatedbrassfor refrigeration

The Parker Sporlan Modulating 3-Way (MTW) valve allows control of refrigerant flow through two outlet ports. Two valve pistons are attached to a connecting rod and also to the stepper motor. As the MTW valve modulates, one port opens and the other port closes. The movement of the valve pistons relative to the two ports is inversely proportional. The MTW is constructed from a forged brass body for durable field operation, and uses a high quality 42 mm stepper motor Features/Benefits: • Improved performance from modulated control • Reduction in number of modulation valves required per system • Simplified system piping reduces installation time and material • Single actuator reduces control and wiring complexity Applications: • Dehumidification • Reheat • Heat Reclaim
