The PURMO rv-339452 is a 1/2 inch straight thermostatic radiator shut off valve finished in chrome. It is part of the Ecostyle product line from PURMO, a manufacturer with a long-standing reputation in hydronic heating systems. This valve is designed for use with panel radiators and tubular radiators in residential and light commercial heating installations. HVAC technicians and plumbers rely on thermostatic radiator valves to control the flow of hot water into individual radiators, allowing each room to be heated to a set temperature independently. This type of zone control improves comfort and reduces energy consumption by preventing overheating in unoccupied spaces. The rv-339452 features a straight body configuration, meaning the inlet and outlet ports are aligned on the same axis. This makes it the right choice when the supply pipe runs directly beneath or alongside the radiator connection. The 1/2 inch connection size is one of the most common in residential hydronic systems, making this valve compatible with a wide range of existing installations. The chrome finish provides a clean, professional appearance that blends well with modern and traditional radiator styles. Thermostatic radiator valves like this one work with a separate thermostatic head or actuator, which senses ambient room temperature and automatically modulates water flow through the valve body. This valve provides the shut off function as well, allowing the technician or homeowner to fully close the water supply to a single radiator for maintenance or replacement without draining the entire system. PURMO Ecostyle valves are built to handle the pressure and temperature demands of standard closed-loop hydronic heating systems. This product is a dependable choice for new installations and retrofit projects alike.
The PURMO rv-339452 Ecostyle straight thermostatic radiator shut off valve delivers reliable flow control and shut off capability in a 1/2 inch chrome-finished body. It is built for hydronic heating systems where individual room temperature control and easy maintenance access are required.
