ONE-WAY VALVE - Brass Body, Anti Back-Flow for AC/Heat Pumps
Six core advantages that keep your refrigeration system protected around the clock
Refrigerant flows only one way and the valve closes automatically in reverse, stopping media back-flow.
Premium brass body with stainless-steel core and spring resists corrosion and high pressure for long life.
Safe working pressure of 3.5MPa meets high-pressure demands of AC and refrigeration.
Designed for reversible AC, pairing with a capillary to auto-switch cooling and heating.
Connections can be made to your dimensions to fit different AC brands and models.
A lightweight core and precisely calibrated spring respond instantly to flow reversal with no delay.
