Ball Valves
Ball Valves are the three types of rotary valves used in industrial plants. They are widely used in fluid-handing 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 Plants, Textile Mills and Food Processing Plants. In general/
Ball valves offer many advantages when contrasted with other types of valves:
-
They provide superior ease of operation.
-
They can maintain and regulate high volume, high pressure and high temperature flow.
-
Most ball valves offer rugged construction providing with a long time service life, and a comparable low cost.
Gate Valves
Gate valves are used when a straight-line flow of fluid and minimum restric¬tion is desired. 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. 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.
Control Valves
Control valves are valves used to control conditions such as flow, pressure, temperature, and liquid level by fully or partially opening or closing in response to signals received from controllers that compare a "setpoint" to a "process variable" whose value is provided by sensors that monitor changes in such conditions.
Safety Valve
The Pressure Relief Valve is a valve mechanism for the automatic release of a gas from a boiler, Pressure Vessel, or other system when the pressure or temperature exceeds preset limits. It is part of a bigger set named Pressure Safety Valves (PSV) or Pressure Relief Valves (PRV).
Safety valve should be limited to compressible fluid application (gas, vapor, steam).
The two general types of protection encountered in industry are thermal protection and flow protection.
For liquid-packed vessels, thermal relief valves are generally characterized by the relatively small size of the safety valve necessary to provide protection from excess pressure caused by thermal expansion. In this case a small valve is adequate because most liquids are nearly incompressible, and so a relatively small amount of fluid discharged through the relief valve will produce a substantial reduction in pressure. Flow protection is characterized by safety valves that are considerably larger than those mounted in thermal protection. They are generally sized for use in situations where significant quantities of gas or high volumes of liquid must be quickly discharged in order to protect the integrity of the vessel or pipeline.
Butterfly Valve
The Butterfly Valve, one type of which may be used in a variety of systems aboard ship. These valves can be used effectively in freshwater, saltwater, lube oil, and chill water systems aboard ship. The butterfly valve is light in weight, relatively small, relatively quick-acting, provides positive shut-off, which can be used for throttling. Butterfly valves are relatively easy to maintain.
We offer different kinds of valves to our customers and here you can find information of some kinds, for any further question regarding a different type of valve please contact us.
Globe Valve
Globe valves are probably the most common valves in existence.
The globe valve derives its name from the globular shape of the valve body, however, positive identification of a globe valve must be made internally because other valve types may have globular appearing bodies. Globe valve inlet and outlet openings are arranged in several ways to suit varying requirements of flow.
Common type globe valve bodies can be a straight flow, angle-flow or cross flow type. Globe valves are used extensively throughout the engineering plant and other parts of the ship in a variety of systems.
