3 Way Ball Valve Triple Offset for Chemical / Power / Light Textile Industry
WCB Pneumatic piston triple offset carbon steel on-off butterfly valve
General
ZSHWE/ ZDRWE Series triple offset butterfly valve provides a bidirectional bubble tight shut-off to API 598. This geometry ensures that the disc seal contacts the seat only at the final shut-off position without rubbing or galling, providing a torque generated resilient seal with sufficient “wedging” to ensure a uniform seal contact. Our butterfly valves are widely used in the chemical, power, light textile, food, pharmaceutics, pulp and paper and other severe application.
Specification:
Nominal Pressure: Class 150lb,300lb
Nominal diameter range:DN801200(3”48”)
Fluid temperature range:-60+450
Flow characteristic is approximate equal percentage.
Characteristics
- One-piece casted body with the feature of compact structure and lightweight
- The triple offset valve advanced design features three-way eccentricity and unique elliptical seat geometry ensuring compressive sealing around the entire seat and a tight, bubble free valve.
- Sealing ring design is novel, concise, free repair
- Stainless steel and graphite laminated seal ring provides reliable, zero leakage, bi-directional shutoff
- Triple offset structure ensure non-rubbing rotation, minimizing torque required and maximizing seat/seal ring lifetime
