A media control valve includes a body, a plunger assembly of multiple components housed in the body with a plunger control valve cap assembly secured to the body for housing a control knob. The body and the plunger assembly include resilient seals between adjacent multiple components of the body and the plunger assembly, respectively, to permit relative movement therebetween during assembly and use. The media control valve includes a diaphragm which acts as a membrane that physically isolates and seals the chambers above and below. The spool sleeve design of the valve has all of the plunger seals and bushings held within the sleeve. Once the spool sleeve is removed, the replacement seals and bushings can be replaced and inspected with relative ease due to the accessibility at both ends of the sleeve. |
