AQ Pressure independent thermostatic valves

For automatic hydronic balancing at the radiator in central heating and cooling systems with closed circuits. Installation in the supply pipe. The Q-Tech valves are ideal for retrofitting and refurbishment of existing heating systems, as complex calculations of preset values are not necessary. The volume flow is kept constant even if the differential pressure in the system fluctuates. The flow range can be variably adjusted between 0.05 to 0.75 GPM. A corresponding presetting key is included.
The AQ thermostatic valves are available in angle, straight, reversed angle and double angle versions.
The body of the valve is made of brass and the surface is nickel plated. The stem is made of stainless steel.
