Axial Flow Control Valve is designed for special applications requiring high flow capacity, the precise control from a linear motion closure member, and reduced turbulence and vibrational effects. An ideal application is centrifugal compressors, as commonly used in gas transmission compressor stations, petro-chemical installations etc. To protect the compressor, the anti-surge valve control valve must open very fast and eject the surge. These valves have to be fast acting but also have high capacity and anti-noise designs. The size range is from 4" to 24" and the temperature range is from -50 to 250 C.

23E PTFE-Lined Rotary Plug Control Valve is designed for general service application up to the limits of the ANSI 150 pressure class rating. These general service applications focus on extremely corrosive media found in chemical processes. The Pfeiffer 23e design increases flow capacities but also reduces the pressure recovery factor making the design more susceptible to cavitation, flashing, and flow noise generation. The design of this rotary plug allows for bi-directional flow with flow pushing plug out of seat, the preferred direction for control valve applications and flow pushing plug into seat, the preferred direction for shut-off applications. The size range is from 1" to 4" and its temperature range is from -10 to 200 C.

Type 3349 Aseptic Angle Control Valve is designed for the strict sanitary requirements of the food, beverage, and pharmaceutical industries that includes the use of USP-VI diaphragm. The valve body is designed without cavities, having a smooth, polished, satin, or mirror finish on internal and external surfaces, and the stem guide is sealed by a diaphragm. A test connection enables the diaphragm to be monitored for leakages. Its size range is 1/2" to 4" and the temperature range is 0 to 160?.

10E PTFE-Lined Centric Butterfly Valve is designed for general service applications up to the limits of the ANSI 150 pressure class rating. These general service applications focus on extremely corrosive media found in chemical processes. It can be assembled with a pneumatic, electric, hydraulic, or electro-hydraulic actuator. These control valves are designed according to the modular assembly principle, can be equipped with company's actuators and valve accessories such as positioners, limit switches, and solenoid valves. The size range is from 2" to 16" and the temperature range is from -50 to 200 C.

Type 3246 Cryogenic Control Valve is designed for cryogenic service applications up to the limits of the ANSI 900 pressure class rating. Also included is a long insulating section as well as a circulation inhibitor to minimize the effects of the medium flow in the insulating section. These control valves are designed according to the modular assembly principle, can be equipped with the company's actuators and valve accessories such as positioners, limit switches, and solenoid valves. It has size from 1/2" to 10" and the temperature range is -196 to 65 C.

Jacketed Plug Valve is provided with full jacketed design and has multiple connection for proper jacket drainage and is specially designed for circulation of hot or cold liquid or gas. The bi directional flow inline PTFE sleeve surrounds the plug unique body & plug design for low torque operation and further the self-sealing design is suitable for vacuum service and further it has low maintenance cost. The size is from 15 mm to 300 mm. Its operation can be manual, pneumatic or electric.

Butterfly Valves are widely used for the hydrocarbon, energy and process industries. Its size range is from 2” up to 88“ (DN 50 up to DN 2200) and the pressure rating is ASME 150# to 900#. Its design standard is according to API 609 MESC SPE 77 / 134, BS 5353 BSEN593, ANSI AWWA C504-94. The valves are available in four different types versions such as Double Offset, Triple Offset, Centre Disc, Extended Stem etc.

Gate Valves are used extensively throughout the hydrocarbon, energy and process industries. It have size from 2” up to 88“ (DN 50 up to DN 2200) and the pressure rating: ASME 150# to 2500#. Its design standard is according to API 602, API 600, MESC SPE 77 / 101, MESC SPE 77 / 102, ASME B16.34. It can be designed in a special version suitable for cryogenic service. In this case, all the materials and technical features are designed to withstand minimum design temperature required by the customer, down to cryogenic -196°C.

Lined Ball Valves are robust and created to handle corrosive fluids from -60° C to +200 °C. The body, adapter, ball and stem of the valves are lined as individual components. The body materials are generally cast ductile iron / cast steel and are also available in CF8/CF8M. The lined valves are suitable to operate at full vacuum. The body design minimizes the dead space between the ball, stem and housing. The ball valves are engineered for reliable isolation and control of extremely corrosive, hazardous and high purity process liquids and gases.

Cast Steel Gate Valves are designed and manufactured to provide maximum service life and dependability. The valves opens by lifting a round or rectangular gate/wedge out of the path of the fluid. The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar. The gate faces can form a wedge shape or they can be parallel. Typical gate valves should never be used for regulating flow, unless they are specifically designed for that purpose. It is provided with BS 1414 specification for Steel Wedge Gate Valves (Flanged and Butt-welding Ends) for the petroleum, petrochemical and allied industries.
