VT PTFE precision needle valves
MVT™ PTFE precision needle valves
Downloads
MVT™ Metering valves are constructed of PTFE and PCTFE materials. Non-fluid contacting external parts are made of anodized aluminum. Valves are offered in three conveniently overlapping flow ranges. Safety handle prevents over tightening and facilitates fine metered regulation.
MVT™ valves are useful in regulating the flow of corrosive gases and liquids. They may be used in pressure or non-critical vacuum service and serve as bubble tight shutoff valves.
