Designed for the harshest applications, the Severe-Tek line outperforms other metal-seated ball valves on the market. 1/2" to 36"; larger upon request. Standard temperature ranges of up to 1100F (higher by request), pressures of ASME 150-4500 and higher. Available end connections include hubs, socketweld (ASME B16.11), buttweld (ASME B16/25), raised face and ring-joint, and custom. Each Severe-Tek valve is custom made for each customer and application…
The Flow-Tek series 19 segmented ball valve utilizes a splined stem and V-port ball segment to enable a 300:1 accuracy of rangeability. Metal and soft seats are pressure-energized to enable excellent sealing during low differential pressures. End post and stem bearings are offered with thick-walled metal or composed of PTFE compound supported by metal fabric, all of which offer low friction and maintenance-free operation. http://www.dacriswell.com/valveautomationsolutions.html
The Rotork SI/EH Skilmatic actuators are for safety-critical installations that are benefited with the feature of partial stroke maintenance testing. Valves can remain open to maintain production while the actuator is partially cycled to gather operating diagnostics. Among other safety features is the return spring’s pre-determined safe position overriding all other commands in the event of an emergency shutdown. http://www.dacriswell.com/rotorkiq3actuator.html
Bray's Flow-Tek Automator Series of opposed-piston pneumatic actuators feature rack and pinion with an output torque of 50 to 29,100 lb-in at 80 psi and a temperature range of -40F to +200F. Internal porting eliminates the expense and maintenance of external tubing. The Automator series of pneumatic actuators is suitable for throttling and on/off applications for chemical and numerous other types of media. http://www.dacriswell.com/valveautomationsolutions.html
The Flow-Tek V-Control ball valve is offered for pneumatic, electro-pneumatic, and electric actuation. The V-Control model exceeds Class VI with bubble-tight shut-off and zero leakage. The many features of the V-Control model include the capacity to function with fluids containing fibers and solids. The V-Control is ideal for steam and temperature control.
