Specialty Control Valves

The Baumann 81000 Mikroseal control valve is excellent for throttling of liquid or gaseous media, particularly where wide flow variations are encountered. Its packless design allows for applications where leakage-prone stem packings are not tolerated. A nearly frictionless mechanical force-amplifying mechanism is employed to reduce the travel of the pneumatic or electric actuators. This allows the closure diaphragm to move precisely against the valve orifice to throttle or stop the passing fluid. The same nearly frictionless mechanism, composed of stainless steel and PTFE lined ball bearings and guide bushings, assures very precise positioning with negligible deadband.

Fisher EH series valves are specially designed for high-pressure applications and incorporate proven techniques in flow-stream contouring for higher capacities and in valve trim design for reliability in severe applications. Fisher™ Aerodynamic Noise Attenuation

Whisper Trim I cages offer proven aerodynamic noise control that is effective for vapor, gas, or steam flow applications. The Whisper Trim cage utilizes multiple orifices of a special shape, size, and spacing to minimize noise generated by the flow of vapor, gas, or steam through a control valve. shale gas in spanish Using a Whisper Trim™cage, in conjunction with a properly sized valve body, can substantially reduce the noise level below that of valves with standard trim.

Whisper Trim III cages provide effective attenuation of aerodynamic noise in vapor, gas, or steam applications involving high pressure drops or high pressure drop ratios. Using a Whisper Trim III cage in conjunction with a properly-sized valve body can substantially reduce the noise level of the control application. Aerodynamic noise is generated by the turbulence created in the flow of vapor, gas, or steam as the fluid passes through a control valve. gas in back symptoms Fisher™ Cavitation Control Trims

Fisher Dirty Service Trim is designed for dirty, cavitating services. This trim utilizes a series of flow restrictions and expansions to eliminate cavitation, while allowing up to 19 mm (3/4 in) diameter particulate to pass through without plugging. Each of the trim stages has a successively larger flow area. The result is very efficient operation because typically 80 percent of the overall pressure drop is taken in the initial stages, where there is little danger of cavity formation which could result in cavitation.

Fisher DST-G trim is specially designed for clean or dirty services where the fluid has dissolved gases that are released from a solution due to a reduction in pressure (outgassing). Outgassing typically causes two types of damage: cavitation and erosion by the fluid stream. DST-G trim stages the pressure drop, similar to the DST trim, to prevent cavitation. Erosion is controlled by the lower cage in this trim, which separates the flow stream into smaller, lower energy jets that are less likely to cause damage. This trim also has the ability to pass particulate up to 6.35 mm (1/4 in) in diameter.

The Fisher TBX-T desuperheater can be used in many applications to efficiently reduce the temperature of superheated steam to the desired set point.

Typical applications include main steam reducing valves and compressor bypass valves. FB valves are also commonly used for sour gas applications in petrochemical and gas processing plants. Fisher™ Polymer Flow Control

The Fisher high viscous polymer (HVP) series control valve is used extensively by the polymer industry. These processes generally require the valves to operate at and maintain high temperatures to assure that the polymer fluid flows freely. The HVP valve can provide integral valve body passages through which a heat transfer fluid is pumped to keep the valve and process fluid heated. Forged and fabricated valve body styles are engineered to meet your process and piping requirements. Standard valve body and trim designs can be adapted to exactly match specifications Fisher™ Diffusers

A complete line of Fisher inline diffusers provide optimum noise attenuation where valves can contribute substantial noise. When installed, the total pressure drop of the system is divided across the valve and diffuser. This enables the valve to operate at a lower pressure drop ratio, thereby lowering the noise level generated from the process flowing through the control valve. Options include: the 6010 with integral outlet head, the 6011 pipe style, and the Whisper Disk.

Fisher 6012 vent diffusers offer proven noise and vibration control in sky vent applications. gas monkey bar and grill A vent diffuser places back pressure on the control valve while venting process to the atmosphere and shares the total pressure drop with the vent valve. This reduces the vent valve noise and noise at the atmospheric vent point. Fisher 6013 vent diffusers come with an outer shell attached for use in sky vent applications in power plants.
