The SRD991 Intelligent Valve Positioner offers the most advanced technology available on the market today.
The technology includes, among others, an infrared interface for wireless operation and configuration, a multi-lingual full-text
graphic LCD and an availability with the choice of all in the process automation applied communication protocols. It offers enhanced
applications and methods to analyze recorded stroke data. All the diagnostics features can be easily configured and displayed
by the Positioner DTM (VALcare). Moreover, the Positioner DTM enables editing a complete health report of the valve with all data
of configuration and diagnostics. The SRD991 also has the capability to control a Partial Stroke Test (PST) that offers operators a tool to identify the trouble-free function of ESD (Emergency Shut Down) valves. Learn More
The SRD960 RCV Universal Positioner offers the most advanced technology available on the market today. This includes among others an infrared interface for wireless operation and configuration, a multi-lingual full-text graphic LCD and an availability with the choice of all in the process automation applied communication protocols. It offers enhanced applications and methods to analyze recorded stroke data. All the diagnostics features can be easily configured and display by the Positioner DTM (VALcare). Moreover, the Positioner DTM enables to edit a complete “health” report of the valve with all data of configuration and diagnostics. The SRD960 has also the capability to control a Partial Stroke Test (PST) that offers operators a tool to identify the trouble-free function of ESD (Emergency Shut Down) valves.

The SRI990 RCV Analog Positioner with analog input 4...20 mA is designed to operate pneumatic valve actuators. It offers an easy
adjustment by means of switches and potentiometers. The modular structure of this positioner series enables conversion from an analog to an “intelligent” positioner by exchanging the electronics. Learn More
The Type 755 actuator is a pneumatically operated, spring opposed diaphragm actuator designed specifically to fit the RESEARCH Control Valve body-bonnet assembly. The unit is available in two sizes: one to fit the 1/4" valve and a larger version to fit the 1/2" through 1" valves. Learn More
The Type 755 actuator with integral, top-mounted positioner is a pneumatically operated, spring opposed diaphragm actuator designed specifically to fit the RESEARCH Control Valve body-bonnet assembly. The unit is available in two sizes: one to fit the 1/4" valve and a larger version to fit the 1/2" through 1" valves. Learn More

The Model EVA-1 is a small, electronically controlled valve actuator developed specifically to fit 1/4 inch to 1 inch Research Control Valves. Its accurate positioning and compact size make it especially suited to flow control in research and small process applications. Learn More
The EVA-100 & EVA-200 are multi-featured actuators with the
capability to accept analog control signals. The design provides
smooth, highly accurate positioning, with positive positionlock
when not in motion. These rugged actuators will withstand
the most adverse environmental conditions. The EVA-100 &
EVA-200 were developed specifically to fit all RESEARCH
CONTROL Valves including the larger Model 9000 & 9100.
Their accurate positioning and high thrust makes them well
suited for all research and process applications. Learn More
Magnum Series piston actuators use low volume and long stroke to maximize bleed and feed rates. Externally mounted spring return modules minimize residual volume and maximize speed of response. This low volume translates into high speed of response.
Leslie's DPS positioner, derived from Leslie's patented PMC electro-pneumatic controller technology, provides ultra-fast, stable response using a pulse modulated output and a non-mechanical, optical/digital stem position feedback.
