PLUG VALVES

Special Design Features

  • ACT high pressure plug valve bodies are made from alloy steel forgings which are designed to variety of end connections to be integrally machined

  • ACT plug and inserts are designed to resist abrasion and corrosion

  • ACT high pressure valves can be easily adopted for hydraulic or pneumatic These configurations are designed for integration with complete manifold systems

  • We manufacture in compliance with API-6A & API-Q1

  • ACT high pressure plug valves range is up to 15000 PSI

  • 3″ & 4″ Fig-1502 Plug Valves can be supplied with gear operated handel

LOW TORQUE PLUG VALVES

ACT manufactures high pressure plug valves in sizes 1″, 2″, 3″ & 4″ pressure rating up to 15,000 PSI WP. ACT plug and inserts are designed to resist abrasion and corrosion. ACT high pressure plug valve bodies are made from alloy steel forgings which are designed to variety of end connections to be integrally machined. Plug valves can be operated either manually, gear operated or hydraulic actuated. ACT produces Low torque model and Top entry model.

Operating Principle

  • The plug rotates 90° (1/4 turn) for rapid full open or close This reduces erosion due to throttling action.

  • To ensure a uniform clamping action for the initial pressure seal, the valve body is tapered.

  • To ensure a continuous seal becomes more effective as differential pressure increases, the plug and inserts float downstream with pressure differential caused by the initial seal.

  • The relationship between the seal and the bearing areas is such that the torque required to operate the valve is minimized.

  • To eliminate the need for thrust bearing to reduce friction, the plug is balanced by identical stem seals.

Operating Principle

The ACT TE high pressure Plug Valve is a lubricated, straight pocket, quarter-turn plug valve for rapid full open or close operation. The valve cavity is straight to ensure low-torque operation and uniform sealing of the components at the full range of pressures. Inserts are provided with dual seal. The ACT TE Plug Valve and replacement parts are engineered to provide low operating torque and resistance to the toughest abrasive and corrosive conditions.
