The MD Series of rotary feeder valves from ACS Valves are constructed with an 8-vane rotary valve that ensures proper pressure sealing at the inlet and outlet flange. The optimal seal can reduce compressed air loss by up to 28 CFM/year, notes the company. The MD Series housings are CNC-machined to precise tolerances; eliminating axial shaft movement, seal leakage, and shortened bearing life. Maintenance cycles are further extended with an outboard bearing design that removes the bearings from the path of damaging and contaminating materials, and protects the bearings in high temperature applications to 750 F, while easily managing application pressure differentials up to 15 psig. ACS Valves MD Series rotary feeders are available in cast iron, or cast 304 or 316 stainless steel. Seven valve sizes are available from 4 to 16 in. Rotor configurations include: closed-end, metering, shallow-pocket, Teflon-coated, and adjustable-tip. Adjustable rotor tips are available in EPDM, hardened steel, stainless steel, bronze or polyurethane. Interior surface coating options include: hard chrome, tungsten, and Teflon.
