Fisher™ Rotary Control Valves
When capacity and performance are the requirements Fisher rotary control valves are the answer. Popular rotary valve product designs include segmented ball, full bore pipeline, eccentric plug, and high performance butterfly.
Segmented Ball Control Valves
Fisher Vee-Ball™ V150, V200, V300 Control Valves
The Fisher Vee-Ball control valve is your best choice for performance and cost-effectiveness across a broad range of applications. The precision-machined parts and pressure-balanced seal designs allow smooth, precise valve operation.
Fisher Vee-Ball™ V150S Flanged Control Valve
The Fisher Vee-Ball V150S control valve offers a rugged construction, highly wear-resistant trim materials, and an unrestricted straight through flow path which makes this valve ideal for controlling the most abrasive of slurries. The design is particularly effective in minimizing erosive damage to the adjoining pipework, thereby providing greater operational safety and service life.
Ball Control Valves
Fisher V250 Control Valve
The Fisher V250 control valve is a heavy-duty, flangeless throttling ball valve often used to control flow in gas transmission lines, gas distribution, and liquid pipelines. Available with a single ball seal, flow ring, or dual-seal construction.
Fisher V260 Control Valve
The Fisher V260 is a full bore control valve designed from the ground up with features for optimized pressure, flow, and process control. An integral drilled attenuator controls noise and vibration from high pressure drop liquids and gases. The splined shaft connection to the actuator reduces lost motion.
Fisher V270 Full-Bore Ball Control Valve
The Fisher V270 is a three piece, trunnion mounted, full-bore control valve designed from the ground up with features for optimized pressure, flow and process control. The V270 full-bore ball valve is designed for automated control in bypass, batch, monitor, and emergency shutoff service applications, and it presents little or no restriction to flow. The V270 full-bore ball valve is available with composition seals, and process type live-loaded shaft packing for improved service life and lower emissions.
Eccentric Plug Control Valves
Fisher V500 Eccentric Plug Valve
The Fisher V500 rotary control valve combines globe valve ruggedness with the efficiency of a rotary valve. It is designed to control erosive, coking, and other hard-to-handle fluids, providing either throttling or on/off operation.
Fisher CV500 Eccentric Plug Valve
The Fisher CV500 valve combines the rangeability of the cammed, segmented V-notched ball, with inherent ruggedness in the heavy duty bearings, seals, and body. This combination provides a balance of erosion resistance and pressure control for gas and liquids.
High Performance Butterfly Control Valves
Fisher Control-Disk™ Rotary Valve
The Control-Disk rotary valve offers excellent throttling performance. An equal percentage flow characteristic provides an improved throttling range comparable to that of a segmented ball valve. This improved capability allows you to control closer to the target set point, regardless of process disturbances, which results in a reduction in process variability.
Fisher 8532 High Performance Butterfly Valve
The Fisher 8532 high performance butterfly valve offers outstanding performance under extreme pressure and temperature conditions. The 8532 valve maintains tight shutoff, is available in a fire-tested construction, and can be specified for cryogenic applications. Available as either a flangeless (wafer style) design, single flange (lugged), or Double Flanged design.
Fisher 8560 High Performance Butterfly Valve
Fisher 8560 butterfly valves is a reliable, high performance control valves suitable for throttling applications requiring extremely low leakage rates.
Fisher 8580 High Performance Butterfly Valve
The Fisher 8580 high performance butterfly valve provides the capability for enhanced shutoff and features an eccentrically-mounted disk with either a soft or metal seal. Experience excellent throttling and on/off performance with this control valve.
Fisher 8590 High Performance Butterfly Valve
The Fisher 8590 high performance butterfly valve maintains tight shutoff and can be specified for a wide range of pressure and temperature conditions. The 8590 valve is available in a lugged body design. A splined shaft can combine with a variety of spring-and-diaphragm or pneumatic piston actuators and a square or keyed shaft can combine with a variety of handlevers, handwheels, or pneumatic piston diaphragm actuators.
Fisher A31D Double-Flange Butterfly Valve
The Fisher A31D is a double-flange, high performance butterfly valve featuring either a splined drive shaft or a keyed drive shaft. The A31D is used in throttling or on/off service and is available in NPS 3 through 12, CL150 and CL300.
Fisher A31A Cryogenic High Performance Butterfly Valve
The Fisher A31A cryogenic high performance butterfly valve is designed for extreme temperature, cryogenic services and features a valve body extension which positions the packing system and the actuator away from the extreme temperatures. The valve also features a metal NOVEX seal providing tight shutoff, low operating torques, and the rugged durability needed for cryogenic service.
