Product information

Description

Straight radiator shut-off valve Perfexim PHA-031 with G1/2 threaded connection, nominal diameter DN15 and pressure rating PN10 is designed for isolation and flow control in hot-water radiator and central heating installations. The valve provides a compact, inline solution for shutting off a radiator during maintenance or for balancing individual radiators. Its straight body and standard G1/2 connection make it compatible with common radiator inlet fittings and simple to install in residential and light-commercial systems.

Advantages

The Perfexim PHA-031 offers a reliable closed/open function and stable flow regulation for single-radiator control. Constructed for compatibility with standard 1/2" radiator fittings, the valve supports straightforward installation and replacement without system modification. Its PN10 pressure rating is suited to typical domestic heating circuits, while the straight design minimizes space requirements and simplifies piping alignment.

Suitable for

  • Isolation of individual hot-water radiators during maintenance
  • Balancing flow to single radiators in central heating systems
  • Retrofit or replacement of 1/2" radiator inlet valves
  • Compact installations where straight inline connection is required

Key specifications

  • Connection thread: G1/2 (standard 1/2" radiator fitting)
  • Nominal diameter: DN15
  • Pressure rating: PN10
  • Orientation: straight, inline valve body
  • Application: hot-water radiator and central heating systems

How to use

Install the valve in the radiator inlet line, ensuring thread compatibility with the radiator or adapter. Apply appropriate thread sealant or tape to the male threads as recommended for heating systems, then tighten to achieve a secure, leak-free connection without over-torquing. Use the valve spindle to shut off flow to the radiator for maintenance or to partially close for flow balancing. After adjustments, check for leaks and verify correct operation under normal system pressure and temperature.

Usage recommendations

For reliable operation, ensure the heating system is drained or isolated according to local practice before removing or replacing valves. Use compatible fittings and follow torque specifications to avoid thread damage. Periodically inspect valves for signs of corrosion or leakage, and operate the valve spindle occasionally to prevent seizing in long-term installations.
