Wedge gate valves differ from parallel gate valves in that the closure member is wedge-shaped instead of parallel, as shown in Figure. The purpose of the wedge shape is to introduce a high supplementary seating load that enables metal-seated wedge gate valves to seal not only against high, but also low, fluid pressures. The degree of seat tightness that can be achieved with metal-seated wedge gate valves is therefore potentially higher than with conventional metal-seated parallel gate valves.

This series can also be adapted to the choke valve application and again fitted with a selection of trim designs to suit each application in conjunction with the angle body configuration. This range can be fitted with standard and severe service trim designs. In conjunction with this the trims could be supplied manufactured in hard metal for potentially erosive applications.
Learn Morebutterfly control valve
FCT Butterfly Control Valve
FCT Concentric Butterfly Valve is designed and developed to use in process engineering and industrial application where only a small leakage (Class IV) is allowed in the closed position or where an elevated temperature or an arduous service means a soft seal is not practical. FCT 'Step-Vane' and 'Swing-Through-Vane' Butterfly Control Valves have been designed and developed for applications where leakage in the closed position is not the problem, but the control of the amount of liquid or gas through the pipe line is paramount. These valves provide excellent throttling performance. These Series Butterfly Control Valves (with Anti-Cavitation/Low Noise Trim) have been designed and developed by FCT to use in process engineering and industrial applications where the effect of cavitation (due to high liquid pressure drop) cannot be eliminated/handled by Concentric Butterfly Control Valves.

Learn Moreeccentric rotary plug control valve
FCT Eccentric Rotary Plug Control Valves
FCT Eccentric Plug Rotary Control Valves are designed for on/off and throttling applications. The plug is offset to the shaft center-line. This allows the plug to break free of the seat ring immediately upon initial rotation of the shaft. Since there is no sliding contact between the plug and seat ring throughout travel, seat ring life and shutoff integrity are greatly enhanced. These valves are designed to overcome the problems of harsh, high velocity and high temperature processes, and they also provide accurate, reliable control in a broad range of applications, such as high and low pressure steam, clean/dirty corrosive liquids & gases, erosive and abrasive slurries etc.
Learn Morediaphragm control valve
FCT Diaphragm Control Valve
FCT diaphragm valves are used on shut-off and throttling service for liquids, slurries and vacuum/gas. The seal is achieved by a flexible membrane, usually elastomer, and possibly reinforced with a metal part. The membrane is tensed by the effect of a stem/compressor with lineal movement until contact is made against the seal of the body. The operating parts of the diaphragm valve are isolated from the flow. This makes this valve suitable for viscous flows and also hazardous, abrasive and corrosive flows as its sealing system avoids any contamination towards or from the environment. Diaphragm valves are available in a wide variety of metals, solid plastics, plastic, rubber and glass linings. They are well suited to the handling of multiple chemical applications both clear fluids as well as slurries. The diaphragm valve has an extended use for applications at low pressures and slurry fluid where most other kinds of valves corrode or become obstructed.

FCT Emergency Shut Down Valves - ESD Valve
FCT Emergency Shut Down Valves (ESDV, ESD, ESV, SDV) are used to isolate pressure and flow from a particular source during an overpressure situation or detection of a dangerous event. ESD valves are integrated into the design of the plant system equipment and can be installed in-line to any location upstream, midstream or downstream. • Immediate control of overpressure, high liquid level or both with integrated design • Integrated control panel by FCT • Pneumatically or hydraulically operated • Upstream installation flexibility due to connective design The emergency shutdown function is always performed by an emergency shut down valve. An emergency shut down valve (also referred to as SDV or Emergency shutdown valve, ESV, ESD, or ESDV) is an actuated valve designed to stop the flow of a hazardous fluid upon the detection of a dangerous event. This provides protection against possible harm to plant team, equipment or the environment. ESDV form part of a Safety instrumented system. The process of providing automated safety protection upon the detection of a hazardous event is called Functional Safety which FCT has pioneered for the last three decades. FCT offers a wide family of shutdown valves, actuators and positioners are engineered to prevent catastrophic incidents when deviations in critical processes occur.

Learn Moremotor operated valve (mov)
Motor Operated Vales-MOV
The FCT Motor Operated Valves (MOV) family of valves are an important item of Plant & Piping system. These valves are generally of large size and are used for different applications such as pump discharge etc. Motor Operated Valves are often called as On-Off valves as the motors serve the purpose of fully opening or fully closing valves in pipelines. For example, cooling water lines, process pipelines where regulation of fluid is not required, motor operated valves can be used to fully allow or fully stop the fluid flow. These valves are not used for throttling or precise control / regulation purposes as they serve mainly On-Off service application. Motor operated valves can be of various types e.g. Gate/ Ball/ Butterfly etc. with actuator control.
