Product details

NSV Forged Lubricated Plug valves Designed for Crude oil, Oil, Natural gas handling and transmission lines. Considered a high maintenance plug valve, they are often used in applications that have infrequent operations. Lubricated plug valves perform well in processes that utilize fluids which carry mildly abrasive particles such as dirty upstream applications, gas pipeline systems that need bypass valves, and as blow-down valves on valve stations and kicker valves.

STRUCTURAL FEATURES

Construction of Lubricated Plug Valves
The flow media with a pressure is contained and controlled by this system. They are;
Body: Body is a main component of the valve and has provisions for 1)connection to the pipe lines, 2) port opening for flow passage, 3)strength requirements for containment of pressure, 4) seating surface for plug, 5) sealing surface for flow control, 6) affixing geometry for most of the valve components, 7) facilitation of lubrication system, 8) stem sealing, etc.

Plug: Plug has provisions for 1) connection to the operation component,2) port opening for flow passage, 3) strength requirements for containment of pressure, 4) seating surface matching to body, 5) sealing surface for flow control, 6) facilitation of lubrication system, etc.

Covers: Bottom an d Top covers have provisions for 1) strength requirements for containment of pressure, 2) limiting and adjusting geometry for plug movement, 3) facilitation of stem sealing, etc. The bottom cover is bolted onto body with stud and nuts. Two metal diaphram are placed in a recess between body and bottom cover in order to prevent the leakage. Sealant system: Sealant system contains 1) injection nipple, 2) injection check valve, 3) grooved plug, 4) Uper chamber, and 4) grooved body.

Inverted Plug: The plug is mounted in the inverted position and divorced from the stem. The inverted plug design is the solution for preventing the Taper Lock . The plug is adjusted in its position by a adjusting screw in the valve cover.

Primary Seal by Metal-to-Metal Seatings: The primary sealing is achieved by the seating surfaces metal body and seat surfaces.

Secondary Seal by Sealant Action: As a secondary seal, the valve is provided with a lubrication system which allows feeding a special sealant into the valve while the valve is in operation. Besides sealing,the lubricant is to protect the internals of the valve against corrosion and wear as well as reducing the valve torque. Sealant injection system ensures that all seal faces are supplied with thin coat of lubricant and by so doing becomes an efficient secondary seal.
