Product Description

REGIONS SUPPLY BUYING GUIDE

Product details & buying advice

Where liquid can become trapped in a piping section, hydrostatic relief selection depends on that section’s service and pressure requirements.

Product type	Hydrostatic relief valves
Part / SKU	3129K

What to check before ordering

Compare the valve’s medium, pressure setting and connection with the protected section.
Have the system designer establish the installation point and discharge arrangement.
Use the replacement and fitting instructions supplied for the exact valve model.

Service reminder: Order for the equipment being protected. A hydrostatic line-relief valve is not a substitute for the tank’s relief valve.

Have gas-system installation and service completed by qualified personnel. Use the current instructions for the exact model and the requirements that apply at the installation location.

Overview

The Engineered Controls 3129K Hydrostatic Relief Valve is a compact, precision-engineered brass valve designed to protect piping and shut-off valves from the dangers of overpressure due to trapped liquid LP gas ONLY. This is especially critical in pipelines and hoses located between shut-off valves or in the side boss of RegO shut-off valves.

Its automatic reseating design ensures quick recovery after discharge, while the resilient seat disc maintains a “bubble-tight” seal for maximum leak prevention. The 3129K is available in both stainless steel and brass models, with configurations allowing direct vent piping attachment when required.
