Pressure Reducing Valve Herz membranowy 3/4" model 1268212

Membrane-type pressure reducing valve Herz membranowy 3/4" model 1268212 is designed to reduce and stabilise inlet pressure in heating and domestic water systems. The valve uses a diaphragm (membrane) mechanism to provide reliable pressure control, offering compact inline installation and direct compatibility with standard 3/4" pipe fittings. It protects downstream equipment from excessive pressure and helps maintain a steady supply pressure for appliances and fixtures.

Advantages

The diaphragm design ensures stable pressure reduction with minimal maintenance and consistent performance over time. Compact inline construction simplifies installation in existing piping runs and reduces required space. Compatibility with standard 3/4" pipe fittings allows straightforward integration without adaptors. The valve contributes to equipment protection by preventing pressure spikes and reducing wear on taps, boilers and other downstream components.

Suitable for

• Domestic cold and hot water distribution systems
• Residential and small commercial heating systems
• Protecting boilers, water heaters and sanitary fixtures from overpressure
• Retrofit installations where compact inline components are required

Key specifications

• Type: membrane (diaphragm) pressure reducing valve
• Connection size: 3/4" (compatible with standard 3/4" fittings)
• Installation: compact inline mounting within pipe run
• Function: reduces and stabilises inlet water pressure to protect downstream systems
• Application: heating systems and domestic water supply

How to use

Install the valve in the supply line where inlet pressure needs reduction, observing flow direction indicated on the body. Fit using standard 3/4" threaded or soldered connections as appropriate for your piping material and local practice. After installation, set the downstream target pressure according to system requirements, then test the system for leaks and correct operation. Periodic visual inspection is recommended to confirm absence of external leaks and proper functioning.

Usage recommendations

Use appropriate isolation valves upstream and downstream to allow maintenance or replacement without draining large parts of the system. Follow local plumbing codes and manufacturer guidance for pressure settings and installation clearances.
