The 830 and 835 Series two- and three-way motorized control valves (MCV) have integrated linear actuators. Available in bronze or stainless steel, the valves have thread connections of 1/2 to 2 inches. They are available for on-off and modulating requirements. The valves are suitable for aggressive and highly corrosive fluids as well as inert gases, hot water, oils, and steam. They can withstand high flow and pressure requirements of 232 to 580 psi. An anti-blocking feature helps remove debris that may become lodged in the valve seat and might otherwise prevent the valve from fully closing. Valve operation contains two options: a fail-safe spring return that automatically closes the valve in case of power loss and various operational speed times. The valves' zero position can be programmed with the stem fully extended or retracted.
