Please check with us the price and weight The NRT valve is a 2-way pneumatic valve with square passage. Composed of a nylon PA66 actuator and brass valve body, the NRT is suitable for standard and brass-compatible fluids. In the latter case, we recommend that you contact our technicians for more information or consult the compatibility table. Even the NRT version, with fluid inlet under the shutter, is able to avoid annoying water hammers in the system. All versions are equipped with an aluminum upper dipstick that allows you to check the health of the valve. The NRT series valve is used in systems where, due to the temperature, nature and pressure of the fluid, extreme performance is not required.
