Geberit NPW automatic air vent valve: G1/2" nickel-plated 652.438.22.1

Quick vent valve – effective air removal from the installation

The Geberit NPW quick vent valve is a reliable solution for removing air from heating and water installations. Its construction, based on proven technology, ensures quick and effective venting, which translates to optimal system performance. Nickel-plated finish provides corrosion resistance and an aesthetic appearance.

Construction and operating principle

The valve is equipped with a stainless steel spring and a PE float, guaranteeing long-lasting and trouble-free operation. The EPDM seal ensures tightness and eliminates the risk of leaks. The operating mechanism is based on the automatic removal of accumulated air when the pressure in the installation drops below 6 bar – this protects the system from damage caused by excessive pressure.

Installation and application

The valve has a standard G1/2" thread, which simplifies its installation in most installations. The nominal diameter DN 15 makes it ideal for use in installations with medium flow rates. The valve height is 67 mm, allowing it to be installed even in places with limited space. The nickel-plated surface protects against corrosion, which is particularly important in humid environments.
