Perfexim left-hand thermostat valve set PHA-037CM with adjustable pre-set, matte black

Perfexim left-hand thermostat valve set PHA-037CM with adjustable pre-set, matte black is a thermostatic radiator valve designed for left-side installations. The set includes a thermostatic valve with an adjustable pre-set feature that limits flow to balance heat output and maintain stable room temperature on heating radiators in residential and commercial systems. The matte black finish provides a discreet, contemporary look compatible with modern interior schemes.

Advantages

The adjustable pre-set function enables precise flow limitation to prevent overheating and allow individual radiator balancing without additional tools. The left-hand orientation suits radiators with inlet connections on the left side, simplifying installation and ensuring correct valve orientation. A thermostatic control integrates automatic temperature regulation by responding to room temperature changes, reducing manual intervention. The matte black surface offers corrosion-resistant coating and a uniform aesthetic that coordinates with black plumbing and hardware.

Suitable for

• Balancing heat output on single or multiple radiators in homes and apartments
• Left-side radiator inlet connections where a left-hand valve orientation is required
• Retrofitting or replacing existing radiator valves to add thermostatic control
• Commercial spaces with discrete matte-black fittings for consistent interior design

Key specifications

• Valve orientation: left-hand (for left-side radiator connections)
• Control type: thermostatic valve with adjustable pre-set for flow limitation
• Finish: matte black surface treatment
• Application: heating radiators in residential and commercial systems
• Function: automatic temperature regulation and radiator balancing

How to use

Install the valve set on the radiator inlet with the connection on the left side, following standard plumbing practices and ensuring the system is depressurized before work begins. Set the adjustable pre-set to limit maximum flow as required for balancing individual radiators, then attach and adjust the thermostatic head to the desired room temperature. After installation, purge air from the radiator and check for leaks. The thermostatic element will modulate flow automatically according to room temperature, maintaining set comfort levels without continuous manual adjustments.

Usage recommendations

For effective radiator balancing, set pre-sets progressively across the system starting from the farthest radiator and adjust while the heating is operating. Periodically check for scale or debris in older systems and flush the circuit if necessary to maintain smooth valve operation. Use compatible fittings and follow local plumbing codes for installation.
