Product details

NSV Plug valves are valves with cylindrical or conically tapered "plugs" which can be rotated inside the valve body to control flow through the valve,it include sleeve plug valve and lubricated plug valve,normally that’s reduce bore(different with ball valve),but also can make it as full bore design.And the PTFE sleeve plug valve incorporate state-of-the-art PTFE fluorocarbon seat design. With little required maintenance and trouble-free operation, a high integrity bubble-tight seal is provided both in-line and to atmosphere.

STRUCTURAL FEATURES

1.Construction of Sleeved Plug Valves

Basic structure is plug, sleeve,body. Sleeve is inserted and encaged inside the body. Tapered plug is inserted onto the sleeve.The sleeve is acting as a soft seat.And completely surrounds plug creating areal sealing surfaces.Also not permitting any dead space in the flow path. Plug is rotating 90 degree. When it is aligned with the body port, flow is open. When the plug is rotated so that plug port is perpendicular to the body port the flow is blocked.The media kept in the plug while at closed position, will be contained in the plug port only,and when the valve is open again,the flow will flush the out. And no remains.

Plug is tapered. Monolithic design.Wedge action. Lowering 1 mm will result in side pressure vectors.Adjustable. Solid not unstable as pressure dependent.Materials can be upgraded for the plug alone to be better resistive than the body corrosion rate.

Sleeve is also tapered to accepted the configure of plug. They are snuggly fit into the void space created by upper, lower and metal port lips.The PTFE materials are rigid enough, resilient enough, elastic enough. Corrosion resistant.Temperature, pressure.For highly radioactive environment, higher temperatures,several different materials are used.

2.Zero Leakage

The zero leakage stem sealing is achieved by the Threefold Stem Sealing System.
The primary seal is provided by the sleeve. The sealing is so tight that no leakage can be observed even without a valve cover. The secondary and the tertiary seal (top seal package) are provided by a delta ring and a diaphragm made of RTFE ( Rein forced Teflon). The sealing is also so tight that no leakage can be observed even with out a sleeve.
