This 1" straight female radiator valve is a thermostatic valve designed for hydronic heating systems, hot water, and steam applications. This valve, with a body configuration that is straight, has a nominal size of 1" and features female threaded x male threaded end connections. Its body is made of nickel-plated bronze, and the seat material is EPDM, capable of withstanding temperatures up to 248°F. The valve is rated for 150 psi in hot water applications and 15 psi in steam applications. Included in this valve are a valve seat disc and a cartridge. It has a differential pressure rating of 36 psi and a capacity of 70,500 BTU/hour. The valve is designed to be used with T100 controls. It continually monitors and adjusts room temperature, providing consistent comfort and relief from underheating and overheating. This functionality is particularly beneficial in one-pipe steam thermostatic radiator valves, allowing for automatic temperature control in both one-pipe steam or hot water systems. These systems are suitable for free-standing radiators, convectors, and other standard capacity heating units. The valve offers the convenience of not requiring an electrical connection for non-electric actuators and is normally open without control mounted. This design ensures both comfort and energy savings, making it an efficient choice for temperature regulation in various heating applications.
