Control Lined Valves
Rigorously tested, automation-ready lined control valves trusted worldwide for precise modulation, enhanced productivity, and reduced costs in any corrosive process condition. Pneumatic, electric, and hydraulic actuation options across PFA, FEP, PVDF, and ETFE linings.
Automation-Ready Valves for Corrosive Process Control
UNP’s Control Lined Valves bring the same corrosion-resistant body and lining technology as our manual valves — combined with factory-fitted pneumatic, electric, or hydraulic actuators for fully automated process loops.
Each valve ships with ISO mounting pads that simplify actuator integration with positioners, solenoids, limit switches, and digital feedback devices. Whether you’re controlling acid dosing in a chemical reactor or modulating ultra-pure water flow in a pharmaceutical line, our control packages deliver precise, repeatable performance under the most aggressive process conditions.
All valves are 100% hydro and pneumatic tested with optional helium leak testing per BS EN 12266-1, and supplied with full CE/PED documentation for global installation.

5 Control Valve Types in This Category
Every control valve here is factory-assembled with the actuator and accessories of your choice.
Control Lined Ball Valve
Quarter-turn ball valve with pneumatic or electric actuator for on/off and modulating service.
Control Lined Butterfly Valve
Compact disc-type control valve for large-bore corrosive lines with fast response.
Control Plug Valve
Tapered plug actuated valve for tight shutoff and throttling in slurry-laden media.
Control Lined Diaphragm Valve
Bubble-tight isolation with full media separation — ideal for sterile and ultra-pure service.
Control Globe Control Valve
High-rangeability throttling globe valve with linear or equal-percentage trim characteristics.
Choose the Right Liner for Your Media
All control valves available in the same lining range as our manual valves — guaranteeing material continuity across automated and manual portions of your pipeline.
Highest purity, broadest chemical resistance — preferred for pharma & semicon.
Excellent transparency, flexibility, and lower processing temperature.
Superior abrasion resistance and high mechanical strength.
Radiation tolerant, tough, and resistant to mechanical stress.
Cost-effective option for low-temperature corrosive service.
Conductive grades (Dyneon ESDZ, Dupont C 980) for explosive atmospheres.
Multiple Actuation Choices
Each control valve can be supplied with the actuator type that fits your control strategy and site infrastructure.
Pneumatic
Spring-return and double-acting cylinders for fast-response, fail-safe applications.
Electric
Modulating motorized actuators with 4–20mA control signal and positioner.
Hydraulic
High-thrust actuation for large valves and demanding torque requirements.
