Sanitop-Wingenroth Safety Valve with Drain Bend 1/2 inch, Heating Valve, Chrome

Safety valve with drain bend. A safety valve is a must in any heating system. If there is too high pressure within a heating system, the safety valve opens automatically and closes again after the water is empty. This only happens when a certain pressure is reached, which is why the valve is ready to use at any time and in all conditions. Normally valves with a pressure of 6 bar and a connection size of 1/2 inch are used in single-family houses. The larger connection of the valve is the "blow-out" line. It is always a dimension larger than the connection to the heating system, as when the pressure is increased, the excess water must be drained as soon as possible. Product features: With chrome-plated drain bend. 1/2 inch connection. To relieve excess pressure Heating installation. Drain pressure: 6 bar. With 3/4 inch nut and seal.
