The model is a direct-acting valve. It works automatically - the transported substance is passed only in one direction. This principle of operation is achieved by the high-quality operation of the spring, which, depending on the pressure, regulates the open / closed position.

The valve from Waterpro is made of LS-59 brass. The temperature range is from -20 °C to + 100 °C, and the working pressure is up to 25 bar. The valve works with cold and hot water, compressed air and other substances that are not aggressive to the material of the product. Nickel-plated coating (3 microns) makes the detail resistant to corrosion processes.

Waterpro's online catalog also presents ¾" and 1" nickel-plated check valve models and male threaded valves.
