The Type ‘D’ Fig. No. 212 Pressure Reducing Valve is direct-acting, piston balanced, single-seated, diaphragm controlled and spring regulated.
Reduced pressure acting upon the diaphragm controls the opening or closing of the valve against flow in accordance with the regulating spring setting. Reduced pressure setting is unaffected by inlet pressure variations in this piston- balanced valve.
The valve is ideally suited for drop-tight installations of water, air, gas and oil services.
