How to choose
- Type of fitting: a ball valve shuts off the flow, a check valve directs it in one direction, a Y-strainer traps debris, and a safety group protects the system.
- Size and thread: match the size from 1/2" to 2" to the system pipe diameter. Check whether you need a female or male thread. This is shown in the product's dimensional drawing.
- Pressure: select a safety group to suit the system. Central heating versions are rated at 3 bar and domestic hot water versions at 6 bar. Valves and strainers have a maximum working pressure of 10 bar.
- Working temperature: ball valves with a 1" union operate up to 70°C. Check valves and strainers have a range of 5–95°C, while the 1/2"×M10×1 sensor valve has a range of 5–100°C.
- Material and features: choose from brass, steel and stainless steel. Selected safety groups have an automatic air vent, while ball valves are designed to accommodate a thermometer or heat meter sensor.
