Controllers, Positioners, Actuators

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 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

Leslie spring and diaphragm actuators are rugged high thrust units with flanged yoke to bonnet connections for simple maintenance and better access to stem packing. These workhorses of our control valve lines have been proven and perfected for nearly forty years of in-service usage. They are available in four sizes: 35, 55, 85, and 135 in. Learn More
