150mm Bare-Valve Outlet Pressure Regulator, Weld-In Connection Style

These advanced-design, strong-bodied, precision- manufactured MODULAR regulators are superior in their ability to overcome dirt and sticky oil during opening and tight closing. Models are available for nearly every control function requirement of industrial ammonia and commercial halocarbon refrigeration.

Outlet pressure is channelled through an external sensing tube to the outlet pressure control module. The outlet pressure is introduced to the space under the control module diaphragm. When outlet pressure decreases below the outlet pressure setting the range spring forces the control module to open further. As the control module opens, more inlet pressure enters the space on top of the piston forcing the main valve seat to open further and regulate flow. As outlet pressure rises the control module reduces the inlet pressure to the piston and the main valve seat starts closing. The external sensing tube on the 5" & 6" valves must be customer supplied and field installed. A 5 psid (.35 bar g) closing spring is standard on 3/4" through 1 1/4" valves. 

This product is a 150mm HA4A Pressure Regulator with Outlet Pressure Regulation, which includes a weld-in connection style.

Any accessories needed are to be purchased separately; this product does not include a strainer.
