The Fig. 213 is direct acting, piston balanced, single seated and spring regulated.
Operation: The inlet of the valve is in hydraulic balance, ensuring that the downstream pressure is unaffected by fluctuations in the upstream pressure.
Pressure relation is achieved by utilizing the thrust generated by the downstream pressure imposed upon the valve disc, and balancing it with a regulating spring.
The load on the regulating spring is set by the position of the adjusting screw, thereby setting the regulated downstream pressure
Availble: 80mm to 200mm
