## Long description

The Herz pressure relief valve model 1393711 features a 1/2" inlet and a G 3/4" outlet and is designed to protect heating and plumbing installations by releasing excess pressure. Constructed from metal for durability, the valve provides a compact solution for maintaining safe operating pressure in residential and light commercial systems. Its threaded connections suit standard piping and allow straightforward integration into existing circuits where a controlled pressure discharge point is required.
Advantages
The valve ensures automatic pressure relief to prevent overpressure situations, reducing the risk of damage to boilers, radiators and associated piping. Its compact metal body offers corrosion resistance and mechanical strength for long service life under typical operating conditions. Standard threaded inlet and outlet make installation and replacement simple without the need for special fittings.
Suitable for
Domestic central heating systems
Small commercial heating circuits
Hot water and plumbing installations requiring overpressure protection
Replacement of existing safety valves with matching thread sizes
Key specifications
Inlet connection: 1/2" threaded
Outlet connection: G 3/4" threaded
Material: metal body suitable for heating and plumbing applications
Function: automatic pressure relief for protection of system components
Design: compact form factor for installation in confined spaces
How to use
Install the valve in the designated position of the pressure line following the system design and orientation recommended by the installation standards. Ensure that connecting threads are compatible and sealed with an appropriate sealing method (e.g., thread tape or sealant) before tightening to avoid leaks. Position the outlet so that discharged fluid is directed to a safe drain or discharge line. After installation, pressurize the system gradually and verify that the valve remains closed at normal operating pressure and opens at the specified overpressure threshold during testing.
Usage recommendations
Check compatibility with system materials and operating parameters prior to installation. Periodically inspect the valve and discharge line for signs of leakage, corrosion or blockages, and follow local regulations for maintenance and replacement intervals to ensure continued safety and reliable operation.
