- Plug:
- The plug encapsulated rubber in specialized processing method can provide zero leak and be suitable for vacuum working conditions
- The fully-encapsulated rubber provides the best protection against plug corrosion
- When installed, slightly pressing the artificial rubber of PTFE thrust gasket can prevent the abrasion particles entering bearing
- Seat:
- A welded nickel alloy seat on body offers the best corrosion resistance and special design reduces torque to ensure tightness and extend plug lifespan
- Corrosion resistance epoxy seat is also available on common application
- Stem seal:
- Our design combines the advantages of resilient and abrasion-resistant
- Self-adjusting sealing system is not affected by the change of pressure, and keep isolated from plug stem or external torque device
- Limited bolt:
- Adjust travel location of close and open, uniform the indicator on actuator with valve's opening angle
- Torque:
- Rubber encapsulated plug sealing surface matches nickel alloy seat and plug stem locates in body and bonnet, makes relative position of upper and lower stem and sealing surface unchanged
- It ensures continuous low torque operation
- Flow:
- The port design with improved internal contours gives high capacity straight through flow in the full open position
- Reduce turbulence and pressure drop
- At the same time, the capacity of passing solids
- Full port:
- All products in this series (3-36") are full port valves, the full port can provide straight and high capacity flow
- Improved rectangular ports increase the capacity of shut off 100% full pipe area rectangular port provides more flow and avoids the problems associated with the point-to-point seating in valves utilizing a segmented ball design, point-to-point seating attempts to fit a spherical ball segment into a circular seat
- Any vertical or horizontal misalignment results in excessive interference at the initial point of contact which increases wear and prevents the segmented ball from closing fully
- Full port allows pipeline pigging:
- Full opening, the 100% flow port and the straight-through interior body design is able for in-line pigging
