The Plug Valve
The plug valve is used primarily for on–off service and some throttling services. It controls flow by means of a cylindrical or tapered plug with a hole in the center that lines up with the flow path of the valve to permit flow. A quarter turn in either direction blocks the flow path.
The Ball Valve
The ball valve is similar in concept to the plug valve but uses a rotating ball with a hole through it that allows straight-through flow in the open position and shuts off flow when the ball is rotated 90 degrees to block the flow passage. It is used for on–off and throttling services.
The Butterfly Valve
The butterfly valve controls flow by using a circular disc or vane with its pivot axis at right angles to the direction of flow in the pipe. The butterfly valve is used both for on–off and throttling services.

The Gate Valve
The gate valve is a general service valve used primarily for on–off, non-throttling service. The valve is closed by a flat face, vertical disc, or gate that slides down through the valve to block the flow.
The Globe Valve
The globe valve effects closure by a plug with a flat or convex bottom lowered onto a matching horizontal seat located in the center of the valve. Raising the plug opens the valve, allowing fluid flow. The globe valve is used for on–off service and handles throttling applications.
The Pinch Valve
The pinch valve is particularly suited for applications of slurries or liquids with large amounts of suspended solids. It seals by means of one or more flexible elements, such as a rubber tube, that can be pinched to shut off flow.
The Diaphragm Valve
The diaphragm valve closes by means of a flexible diaphragm attached to a compressor. When the compressor is lowered by the valve stem onto a weir, the diaphragm seals and cuts off flow. The diaphragm valve handles corrosive, erosive and dirty services.
The Needle Valve
The needles valve is a volume-control valve that restricts flow in small lines. The fluid going through the valve turns 90 degrees and passes through an orifice that is the seat for a rod with a cone-shaped tip. The Size of the orifice is changes by positioning the cone in relation to the seat.

A Valve is a product rarely noticed by the average person, yet it plays an important role in the quality of our life. Each time you turn on a water faucet, use your dishwasher, turn on a gas range, or step on the accelerator of your car, you operate a valve. Without modern valve systems, there would be no fresh pure water or automatic heat in your home. There would be no public utilities, and beyond wood and coal, almost no energy of any kind. Plastics would be unheard of, as would many inexpensive consumer products.By definition, a valve is a device that controls the flow of a fluid.Today’s valves can control, not only the flow, but also the rate, the volume, the pressure or the direction of liquids, gases, slurries or dry materials through a pipeline, chute or similar passageway. They can turn on and turn off, regulate, modulate or isolate.They can range in size from a fraction of an inch to as large as 30 feet in diameter and can vary in complexity from a simple brass valve available at the local hardware store to a precision-designed, highly sophisticated coolant system control valve, made of an exotic metal alloy, in a nuclear reactor.
Valves can control flow of all types, from the thinnest gas to highly corrosive chemicals, superheated steam, abrasive slurries, toxic gases and radio active materials. They can handle temperatures from cryogenic region to molten metal, and pressures from high vacuum to thousands of pounds per square inch.
The valve is one of the most basic and indispensable components of our modern technological society. It is essential to virtually all manufacturing processes and every energy production and supply system. Yet it is one of the oldest products known to man, with a history of thousands of years.

The double flanged design is suitable for high pressure loading and
is excellently suited for use in heavy industry, shipbuilding and
waterworks.
TECHNICAL DATA
Nominal diameter: DN 50 – DN 1200
FEATURES
- Absolutely tight sealing with flow in either direction
- The valve body and disc are accurately machined which results in
low operating torque and long service life and reliability.
- Triple shaft bearings prevents shaft deflection and guarantees
optimum guidance even after many years of operating service.
- Can be disassembled, material-specific recycling possible.
- Single flange mounting is possible.
- Can be installed in any desired position.
- Maintenance-free
- Fully repairable valve

- Breaking Pressure:
The minimum pressure required to produce flow through a valve.
- Duty Cycle:
100% duty cycle is defined as continuous operation without any damage occurring. For intermittent duty cycle (<100%), alternate energized and de-energized state at regular intervals to allow the valve to completely cool down to room temperature.
F = active concentration / total concentration
- Flow Patterns:
A diagram showing how flow can be directed using a particular valve. (See the “Flow Patterns” box below for further explanation.)
- Normally Closed:
Valve stays closed in de-energized state; opens when energized.
- Normally Open:
Valve stays open in de-energized state; closes when energized.
- Pressure Differential or Pressure Drop:
The difference between the inlet and the outlet pressure through a valve. The outlet pressure is lower than the inlet pressure due to the restriction caused by the valve.
- Three-Way Valve:
Has three ports. Depending on the particular valve, all three ports may be open, two ports may be open, or all ports may be closed.
- Two-Way Valve:
Has a single inlet port and a single outlet port.
- Choose a valve type depending on your application. Our manual valve selection includes ball, check, diaphragm, elliptic, metering, needle, pinch, plug, pressure relief, and stopcock valves. Our actuated valve selection includes electrically actuated ball, elliptic, pinch, proportioning, and general-purpose solenoid valves.
- Consider your fluid type (liquid or gas) and its characteristics to determine compatible valve materials. Teflon withstands many harsh or corrosive chemicals. For safety reasons, always use metal valves for pressurized gases.
- Determine the temperature, pressure, and flow rate under which your valve will be operating. In general, metal valves withstand higher temperatures and pressures than plastic valves.
- For solenoid valves, consider response time and length of time valve will be energized. Continuous (100%) duty solenoid valves are best for frequent on/off cycling. Choose normally closed or normally open depending on the state the valve will be in most often.
- Consider your maintenance requirements. Ball valves resist plugging and are easiest to service.
