gate valve catalog |
| Gate Valve are widely used in fluid-handing systems for flow control. Gate valves are so named because the part that either stops or allows flow through the valve acts somewhat like the opening or closing of a gate and is called, appropriately, the gate. The gate is usually wedge shaped. When the valve is wide open, the gate is fully drawn up into the valve, leaving an opening for flow through the valve the same size as the pipe in which the valve is installed. Therefore, there is little pressure drop or flow restriction through the valve. | |

ball valve catalog |
| Ball Valve are the three different types of rotary valves used in industrial plants. They are widely used in fluid-handling systems for flow control. These types of rotary valves are suitable for corrosive applications. They are used in detergent, pharmaceutical, chemical, rubber, pulp and paper plants, water treatment systems, textile mills and food processing plants, In general, ball valves offer many advantages when contrasted with other valve types. They provide superior ease of operation and can maintain and regulate high volume, high pressure and high temperature flow. Most ball valves offer rugged construction providing for a long service life, and a comparably low cost. Additionally, the design of the regulating element allows the valve to function without the complications of side loads, typical of butterfly or globe valves, and the valve design permits inspection and repair of seats and seals without removing the valves body from the pipeline. | |

Globe Valve catalog |
| Globe Valve are probably the most common valves in existence. The globe valve derives is name from the globular shape of the valve body. They are widely used in industry to regulate fluid flow in both on/off and throttling service. Globe valves consist of the following moving parts - the disk, the valve stem, and the hand-wheel. The stem connects the hand-wheel and the disk. It is threaded and fits into the threads in the valve bonnet. The location of the valve disk in relation to the valve seat allows or restricts flow. The direction of fluid flow through the valve changes several times, which increases the pressure drop across the valve. In most cases, globe valves are installed with the stem vertical and the higher-pressure fluid stream connected to the pipe side above the disk, which helps to maintain a tight seal when the valve is fully closed. | |

Check Valve catalog |
| Check Valve are generally used in drip irrigation emitters and irrigation sprinklers. Composition disc valves are ideal for applications involving gritty liquids. A clapper valve is a type of check valve which is used in fire fighting. Poppet check valves find use in . | |

Butterfly Valve catalog |
Butterfly valve is a type of valve which can be used in a variety of chemical services. They are available with small dimensions allowing for use in areas where space is limited, and they allow a high coefficient of flow. A butterfly valve is composed of body, soft seat or hard seat, disc, stem, packing, notched position plate, and a lever or gear. The seat is under compression when it is mounted in the valve body, thus making a seal around the periphery of the disc both upper and lower points where the stem passes through the seat. Packing is provided forming a positive seal around the stem for added protection in case the seal formed by the seat could become damaged. |

Forged Steel Valve catalog |
Forged Steel Valves are used in Oil Refining and other industrial applications where forged steel material is required. Higher pressures and temperatures are involved and the line size is generally under the size of "2". In other conditions, forged steel valve might be a good choice for better performance, such as system requirements for socket-weld piping and compatibility of media. |
