Q-Tech Automatic hydronic balancing

AQ 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 10 and 170 l/h. 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.

AQH Thermostatic valves

For automatic hydronic balancing in heating and cooling systems with closed circuits. Installation in the supply pipe. The Q-Tech valves with high flow rate (AQH) are ideal for new construction, refurbishment and retrofitting in combination with radiant ceiling panels, fan coils, radiators and other consumers.  Complex pipework calculations 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 35 and 420 l/h. A corresponding presetting key is included.
The AQ thermostatic valves DN 15 are available in angle, straight and reversed angle versions.
The body of the valve is made of brass and the surface is nickel plated. The stem is made of stainless steel.

EQ 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 10 and 170 l/h. A corresponding presetting key is included.
The EQ thermostatic valves are available in angle and straight versions.
The design of the exclusive radiator fittings combines extraordinary shape with outstanding function, especially for modern radiators and bathroom radiators. The body of the valve is made of brass and the surface is chrome plated or white powder coated. The stem is made of stainless steel.

Multiblock TQ Connection fittings with thermostatic valve

The Multiblock TQ connection fitting is a combination consisting of a thermostatic valve and a connection fitting at the radiator. The special QA valve insert makes the fitting suitable for automatic hydronic balancing at the radiator in central heating and cooling systems with closed circuits. The fitting is soft sealing to the radiator. The connection fitting is suitable for connection to radiators with G 1/2 internal thread.
The following functions are available: Infinitely adjustable presetting for automatic hydronic balancing, shutoff as well as draining and filling. The Multiblock TQ connection fitting is available in straight and angle versions and is made of nickel plated brass, the centre distance is 50 mm. Design covers are available in various colours and surfaces (see chapter “Q-Tech Accessories and spare parts”).

Multiblock TQ-RTL Connection fitting with thermostatic valve and return temperature limiter

The Multiblock TQ-RTL connection fitting is designed for the combined use of radiators and surface temperature regulation in two pipe systems. The fitting includes a QA valve insert for automatic hydronic balancing and an RTL controller for return temperature limitation. The room temperature and return temperature are controlled separately. The fitting is soft sealing to the radiator. The connection fitting is suitable for connection to radiators with G 1/2 internal thread.
The following functions are available: Infinitely adjustable presetting for automatic hydronic balancing, shutoff and return temperature limitation for surface temperature regulation. The connection fitting Multiblock TQ-RTL is available in angle version and is made of nickel plated brass. A mounting aid is included in the scope of delivery. Design covers are available in white and chrome plated (see chapter “Q-Tech Accessories and spare parts”).

Multiflex FQ Connection fittings without thermostatic valve

The Multiflex FQ connection fittings are designed for the connection of radiators with integrated valve set. The special QA valve insert makes the fitting suitable for automatic hydronic balancing at the radiator in central heating and cooling systems with closed circuits.

The fitting is soft sealing to the radiator. Depending on the version, the connection to the radiator is either with G 3/4 union nut and insert to radiators with G 3/4 external thread (Eurocone) or with G 3/4 union nut and nipple to radiators with G 1/2 internal thread.

The following functions are available: Shutoff, draining, filling and presetting. The Multiflex connection fitting is available in straight and angle versions and is made of nickel plated brass, the centre distance is 50 mm.
