Pressure reducing valve Herz 1" model 1268213 for water systems

The Herz pressure reducing valve 1" model 1268213 is designed for water systems where inlet pressure needs to be reduced and stabilized to a safe, adjustable downstream pressure. Manufactured by Herz, this valve provides reliable pressure regulation for domestic and light commercial plumbing and heating installations. It helps protect fixtures, appliances and piping from excessive pressure while maintaining consistent supply conditions across varying inlet pressures.

Advantages

The valve offers stable pressure reduction with an adjustable setpoint to match system requirements. Its compact design allows straightforward installation in-line with existing pipework. The device reduces the risk of leaks and damage by limiting transient and sustained high pressures. Materials and construction are chosen for durability in potable water applications, ensuring long-term performance with limited maintenance.

Suitable for

• Domestic water supply systems in single-family homes
• Light commercial properties such as small offices or retail premises
• Protection of household appliances (dishwashers, washing machines) from high inlet pressure
• Plumbing and heating systems requiring stable downstream pressure for valves and fixtures

Key specifications

• Nominal connection size: 1 inch
• Function: pressure reduction and stabilization for potable water
• Adjustability: downstream pressure setpoint adjustable within manufacturer-specified range
• Installation type: inline mounting in supply mains
• Typical application temperature: suitable for normal cold and hot water service (operating temperature range per Herz documentation)
• Flow capacity: sized for domestic and light commercial flow rates (refer to system hydraulic design for exact capacities)
• Materials: corrosion-resistant components suitable for potable water

How to use

Install the Herz 1" pressure reducing valve in the main supply line following local plumbing codes and the manufacturer's installation instructions. Set the valve orientation according to the flow direction marked on the body. Adjust the downstream pressure to the required value using the adjustment mechanism; verify the setting with a calibrated pressure gauge downstream of the valve. After installation and adjustment, check for leaks and confirm stable pressure during typical demand cycles. Periodic inspection and functional checks are recommended to ensure continued performance.

Usage recommendations

For best results, select a downstream pressure that protects fixtures and appliances while providing adequate service pressure for fixtures. Install shut-off valves upstream and downstream to facilitate maintenance and replacement. If water quality is poor or contains abrasive particles, consider appropriate filtration upstream to extend valve life. Follow Herz documentation for maintenance intervals and replacement procedures.
