Helping you find the valve you need for your solar thermal water heating system 

The valves used in a solar thermal water heating system force the water that is above a specific set temperature to other parts of the system, making them a critical component in controlling the flow of fluids, regulating temperature and ensuring the system operates safely and efficiently.  

Our full range of solar thermal valves includes: 

Thermal Balancing Valves 

Designed to control the flow by manual regulator for the solar pumped circuit, our range of balancing valves includes solar flow balancing valves with various size flow meters and capacities. 

Thermal Relief Valves 

Relief valves are an essential safety feature in a thermal solar system, preventing the tank from exploding if the pressure becomes too high. The most popular solar relief valve in the range is the ½” BSP Inlet x ¾” BSP Outlet Solar Safety Relief Valve – 6 bar. 

Thermal Mixing Valves 

Our range of solar thermostatic mixing valves includes valves suitable for pressurised systems or gravity and pressurised systems. 

Solar Check Valves 

Check valves are critical in preventing damage to the heating system, as they prevent the reverse flow of fluid. Our range's most popular check valve is the ¾” BSP Solar, suitable for high temperature solar systems. 

Drain/Fill Valves 

BES offers a wide range of drain/fill valves suitable for high temperature solar systems, including a solar service and commissioning fitting for isolating valves, allowing solar pump stations to be mounted in loft spaces. 

Motorised Valves 

BES’ range of solar motorised valves includes solar diverter valves and solar zone valves that can be used in solar and heating circuits.  

Solar Valves 

The Thermostatic Solar Valve Kit with Bypass is the most popular solar valve available in this selection – it diverts potable domestic hot water from a solar cylinder to control the water temperature. 

Solar Diverters 

Suitable for water heating thermal solar systems, our most popular solar diverter valve can be used with combination boilers or instantaneous water heaters too. 

Recovery Containers 

Solar glycol fluid needs a secure container to be stored in when expelled from the heating system while a solar safety valve actuates. The most popular recovery container we have here at BES is the Safe Valve Solar Fluid Recovery Container, which includes a drain valve.
