12-KINETROL | DOUBLE ACTING ACTUATOR

In modern process automation, consistent and fail-safe valve cycle control is imperative for production output and plant safety. For quarter-turn (90°) valves such as ball, butterfly, and plug valves, conventional rack-and-pinion actuators often struggle with gear backlash, mechanical friction wear, and internal seal degradation during continuous operations.The Kinetrol Model 12 sets the international benchmark in rotary pneumatic valve actuation. 

Kinetrol’s double-acting vane-type rotary actuator Model 12 is robust and durable with its epoxy thermoset powder-coated aluminium alloy casing. The Model 12’s special design, with its one piece integral zinc plated SG iron vane and shaft, makes it highly reliable and efficient.

Key Features

Single Vane Technology – Exceptional Mechanical Reliability:

• An integral vane and output shaft assembly direct-drives the valve shaft without secondary gears or mechanical linkage joints.

• Eliminates mechanical backlash, gear chatter, and uneven wear over years of high-frequency cycling.

Heavy-Duty Die-Cast Enclosure:

• High-integrity die-cast aluminum alloy casing with a durable polyurethane/epoxy exterior finish.

• Excellent resistance against chemical mist, salt spray, and extreme industrial washdowns.

Versatile Operating Actions:

• Double Acting (DA): Generates balanced, symmetrical torque in both opening and closing directions, maintaining high efficiency with minimal air consumption.

• Spring Return (SR - Fail-Safe): Houses Kinetrol’s clockwork-grade spring module to reliably return the valve to a predetermined safe position (Fail-Closed or Fail-Open) upon supply air disruption.

Discrete Modular Integration:

• Direct, bracketless mounting for complete control packages:

  • Discrete Limit Switch Boxes (Weatherproof IP66/67 or ATEX/IECEx Explosion-proof).

  • Pneumatic & Electro-Pneumatic Positioners (4 - 20 mA modulating signal).

  • Direct-mount Namur solenoid valves.

Adjustable Travel Stops:

• External travel stops provide precise angular stroke adjustment (±2° at both stroke endpoints) to guarantee tight bubble shut-off or exact full-bore pipe alignment.

Applications

The Kinetrol Model 12 is specified globally across process industries requiring uncompromising reliability and zero downtime:

• Process Valve Automation: Direct actuation of small-to-medium quarter-turn ball valves, butterfly valves, and eccentric plug valves.

• Food & Beverage (F&B) and Pharmaceuticals: High-cleanliness operations, sanitary filling heads, and CIP/SIP fluid circuits where internal grease leaks must be prevented.

• Chemical, Petrochemical & Energy: Pipeline safety shut-off, emergency shutdown (ESD) stations, and tank farm isolation valves demanding explosion-proof certification and fail-safe return.

• Water & Wastewater Treatment: Outdoor penstock and distribution header control, chemical dosing lines, and aeration dampers.

• Industrial HVAC & Boiler Dampers: Rapid-response modulation of flue-gas, thermal oxidizer, and process combustion air dampers.
