Product details

NSV Jacketed plug valve are designed to control special chemical service where media has to be required within a specified temperature range. The steam jacketed design prevents the media in the body from cooling down. If cool media become solid, the trim parts, plug and stem will be very hard to operate. The steam jacket keep maintaining required temperature of the valve.

STRUCTURAL FEATURES

1.Construction of Jacketed Sleeve 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.

PTFE is an plastic material, even though they are high grade engineering material. All plastics are subject to cold flow.; at higher temperature volume increase,escape to the low pressure area and don’t get back to its original position even after removal of temperature, pressure. But, if they get confined , they would not cold flow. Upper boundary and lower boundary, and 360 port lips.Recessed wall is acting as absorption of inflated volume of PTFE when volume is increased due to temperature.

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.
