Quarter-Turn Control Ball Valves for Corrosive Process Loops
UNP’s Control Lined Ball Valve combines our proven lined ball valve body with a factory-fitted pneumatic or electric actuator. Both Reduced Port and Full Port designs are available, and the ISO 5211 mounting pad accommodates virtually any aftermarket actuator if you want to specify your own.
For on/off automated isolation duty, the quarter-turn ball valve is the fastest and lowest-torque option. For modulating throttle control, pair it with a smart positioner (HART or Profibus) on the pneumatic actuator. V-port balls are available for improved low-flow control characteristics.
The full-port floating ball gives full unobstructed bore for non-fouling flow paths. Reduced port (with stem-integral ball) is more compact and suited to smaller actuator sizes.
Why Choose This Control Valve
- ✓Quarter-turn for fast actuation
- ✓Reduced & Full Port designs
- ✓ISO 5211 mounting standard
- ✓V-port ball available for modulating control
- ✓Chevron PTFE stem seal — zero leakage
Choose Your Actuator Type
Each valve ships fully assembled with the actuator type and accessories that fit your control strategy.
Pneumatic
Spring-return fail-safe and double-acting cylinders. Fastest response, preferred for safety-critical service.
Electric
Motorized actuators with 4–20 mA modulating or on/off control. For sites without instrument air.
With Smart Positioner
Pneumatic actuator + digital positioner (HART/Profibus) for precise modulating throttle control.
