valve features:
Plug
The plug encapsulated rubber in specialized processingmethod can provide zero leak and be suitable for vacuum working conditions. Thefully-encapsulated rubber provides the best protection against plug corrosion. Wheninstalled, slightly pressing the artificial rubber of PTFE thrust gasket canprevent the abrasion particles entering bearing.
seat
A welded nickel alloy seat on body offers the best corrosionresistance and special design reduces torque to ensure tightness and extendplug life. Corrosion resistance epoxy seat is also available on commonapplication.
Stem Seal
Our design combines the advantages of resilient and abrasionresistant. Self-adjusting sealing system is not affected by the change ofpressure, and keep isolated from plug stem or external torque device.
LimitedBolt
Adjust travel location of close andopen, uniform the indicator on actuator with valve’s opening angle.
Torque
Rubber encapsulated plug sealing surface matches nickelalloy seat and plug stem locates in body and bonnet, makes relative position ofupper and lower stem and sealing surface unchanged. It ensures continuous lowtorque operation.
Flow
The port design with improved internal contours gives highcapacity straight through flow in the full open position. Reduce turbulence andpressure drop. At the same time, the capacity of passing solids.
100%Port Area
All products in this series (3”~36”) are 100% eccentric plugvalves. The port is 100% standard pipe area which can provide straightand high capacity flow.
Improved Rectangular Ports Increase the Capacity of Shut Off
100% full pipe area rectangular port provides more flow andavoids the problems associated with the point-to-point seating in valvesutilizing a segmented ball design, point-to-point seating attempts to fit aspherical ball segment into a circular seat. Any vertical or horizontalmisalignment results in excessive interference at the initial point of contactwhich increases wear and prevents the segmented ball from closing fully.
Full Port Allows Pipeline Pigging
Full opening, the 100% area port and the straight-throughinterior body design is able for in-line pigging.
