CS400 Series Pressure Reducing Regulators
Fisher CS400 Series direct-operated, spring-loaded regulators have been engineered to fit a multitude of pressure-reducing applications including commercial and industrial installations. This flexibility is provided by the numerous body sizes and end connections, outlet pressure settings, orifice sizes, as well as the option for internal or external pressure registration.
In addition to application flexibility, the CS400 Series offers multiple overpressure protection options to meet your demands on application requirements.

Self Operation - As the downstream demand increases, outlet pressure registering under the diaphragm decreases allowing the spring to move the diaphgragm assembly downward. Click here to view the animation.
True Monitor with Internal Registration - The Monitor engages and regulates flow. Should demand continue to decrease, outlet pressure will continue to increase and the monitor will close off against the Monitor seat until lockup occurs.

True Monitor with External Registration - In the event that the control line of the Primary Regulator breaks, the pressure registering underneath the Primary regulators diaphragm will decrease causing it to open completely and supply additional flow downstream. Click here to view the animation.
