Camflex II valve helps customers comply with environmental regulations

Company info

Dresser Masoneilan helps customers meet strict environmental emissions standards with the Camflex II rotary globe valve. Featuring a specially-developed Emissions Free (EF) Seal and many other innovative design characteristics, the Camflex II valve reduces equipment emissions that can occur at the valve shaft sealing, or packing, particularly after long-term operation. In control valve construction, a delicate balance must be maintained between a tight seal that prevents potentially hazardous emissions and excessive friction between the seal and the valve stem. High friction can affect a valve’s ability to provide the desired control accuracy which can pose a costly hazard. It can also wear the packing material over time causing leakage and increasing maintenance costs and down-time.

Standard on most Dresser Masoneilan rotary valves, including the Camflex II rotary globe valve, the Dresser Masoneilan EF Seal is efficiently engineered with few components for ideal sealing functionality. It combines a double O-ring sealed packing follower with low-friction tetrafluoroeth-ylene (TFE)-based packing materials for reliable, long-term service that complies with low-emissions standards.
