Pneumatic V-Type Control Ball Valve

Overview

ZSHV Pneumatic V-Type Control Ball Valve is a rotary ball valve with a valve core and seat sealed by metal, or metal-to-PTFE, mating surfaces. It combines the best control characteristics of ball valves and butterfly valves, and can be used either as a regulating valve or as a shut-off valve. Its main features are:

• One-piece valve body with no pipe fittings, unaffected by pipeline or bolt stress; the pressure-containing shell is not affected by sudden pressure surges.
• The V-shaped ball ensures accurate control across the full range even at small flow rates or with high-viscosity media.
• The leak-tight, durable seat is lined at its outer diameter with a PTFE cup or O-ring seal with stainless steel inner core; the seat is made of tungsten-cobalt hard alloy with a relatively large cross-section, and its structure is further reinforced by an alloy corrugated spring.
• When the valve is closed, the V-notch and the seat produce a wedge shearing action that is both self-cleaning and prevents the ball core from seizing, particularly suitable for pipelines subject to scaling, freezing, or media containing fibers and granular solids.

Suitable for high-viscosity fluids, suspensions, pulp and other dirty media containing fibers. The valve is directly connected to the actuator, offering compact structure, small size, light weight, low resistance and stable, reliable operation. Depending on user requirements, the actuator can be configured with UNIC, PSQ, HQ, DHL electric actuators, or GTX, AL pneumatic piston actuators.
