KVA38 spring-loaded electric valve actuator
- Zero deadband — gentler on gas turbines and downstream equipment
- Low maintenance, motorless design
- Eliminates 100% of methane venting gases
- Certified for Class I, Zone 1 hazardous locations
- A direct replacement for pneumatic actuators
Two connections. That’s the whole install.
No air lines, no gearboxes, no positioner cabinet — the KVA38 needs only a power feed and a control signal.
Power + signal. Nothing to compress, dry, store — or leak.

— The next generation
Introducing the next generation of valve actuators
The KVA38 is a general-purpose globe valve actuator designed to meet the needs of the energy and process control industries. Harnessing cutting-edge Shape Memory Alloy (SMA), the KVA38 delivers high force with exceptionally precise linear motion.
Shape memory alloy technology
Providing micron-level precision and accuracy.
Mechanical spring
Fail-closed on loss of power or signal, with a mechanical spring design for maximum safety.
Rated for hazardous locations
Heavy-duty construction, certified to operate in Zone 1 hazardous locations in both the US and Canada.
Industrial interface
Fully electric using 24VDC or 120VAC, with both analog (4–20 mA) and serial (Modbus) control options.
— Zero deadband
Perfect tracking — gentler on everything around it
The KVA38 continuously tracks its position command with zero deadband — no hunting, no overshoot, no correction cycles. That smoothness protects everything downstream, and nothing benefits more than gas turbines: among the most expensive equipment on site to maintain, and directly exposed to every fluctuation in fuel-gas control.
Easier on gas turbines
Steady, precise fuel-gas control means fewer pressure and flow fluctuations ever reach the turbine — protecting the costliest maintenance line item on your site.
Less wear across the loop
The same smooth motion reduces mechanical stress on valve trim, positioners, and piping — extending service life across the whole control loop.
Lower cost of ownership
Fewer interventions and less unplanned downtime deliver the lowest total cost of ownership compared to pneumatic or motor-operated valve solutions.

See how the KVA38 actuator works
The KVA38 leverages advanced Bundled Wire technology to deliver precise linear motion and high force. Fully electric, operating on 24VDC or 120VAC with analog and serial control for seamless integration and certified for use in hazardous locations.
— Energy sector
Redefining process control in the energy sector
As industry moves away from methane-venting pneumatics, the Kinitics Valve Actuator is the ideal all-electric alternative. Featuring a mechanical spring, the actuator provides reliable valve closure in the event of power loss or control signal interruption.
With minimal maintenance needs, the KVA38 delivers the lowest cost of ownership compared to traditional pneumatic or motor operated valve (MOV) solutions.
— Technical advantages
Less infrastructure and lower maintenance than incumbents
- Spring closure — returns the valve to a known position on loss of power.
- 100% duty — constantly follows a position command without taking rests.
- Zero deadband — continuously tracks a position command.
- Low maintenance — motorless design keeps it virtually maintenance-free.
- Low infrastructure — functions without ancillary equipment such as compressors, tanks, and valves.
The KVA offers technical advantages, less infrastructure, and lower maintenance over the competition.
