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:DN80～1200(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；
