Description

A valve is a mechanical device that controls the flow rate, flow direction, pressure, temperature, etc. of a flowing fluid medium. Valves are the basic components in piping systems. Valve fittings, like pumps in technology, are often discussed as a separate category. The valve may be operated manually or with a hand wheel, handle or pedal, and may also be controlled to vary the pressure, temperature and flow rate of the fluid medium. The valve can perform continuous or repeated operations on these changes, such as safety valves installed in hot water systems or steam boilers. In more complex control systems, automatic control valves are used as required by external inputs (I. e., to adjust the changing set point of the flow through the pipeline). The automatic control valve does not need to be manually operated according to its input and setting, so that the valve can accurately control the various requirements of the fluid medium. Valves can also be divided into cast iron valves, cast steel valves, stainless steel valves, chromium molybdenum steel valves, chromium molybdenum vanadium steel valves, dual phase steel valves, plastic valves, non-standard customized valve materials, etc.

◆ Product overview

American standard floating ball valve opening and closing parts (ball) driven by the valve stem, and around the axis of the valve stem for rotational movement of the valve. It is mainly used to cut off or connect the medium in the pipeline, and can also be used for fluid regulation and control. It can no longer be used for cutting off after adjustment. Floating ball between itself compact structure, reliable sealing, simple structure, convenient maintenance, sealing surface and spherical surface often closed state, not easy to be medium erosion, easy operation and maintenance, suitable for water, solvent, acid and natural gas and other general working medium, but also suitable for working conditions of poor media, such as oxygen, hydrogen peroxide methane and ethylene, etc., in various industries have been widely used.

◆ Product overview

1. The valve is an excellent product produced by our company on the basis of digesting and absorbing advanced technology at home and abroad. It has updated design features and can meet the safety and convenience needs of general industrial standards.
2, the sphere is floating, under the action of the medium pressure, the sphere can produce a certain displacement and press on the sealing surface of the outlet end to ensure the seal of the outlet end.
3, the valve rotation 90 ° can be fully closed fully open, open and close quickly. Compared with the gate valve and globe valve of the same specification, the ball valve is small in size and light in weight, which is convenient for pipeline installation.
4, in a variety of valves, the ball valve flow resistance is the smallest, full diameter ball valve is opened, the ball channel, valve body channel and connecting pipe diameter is equal and a diameter, the medium can flow through almost without loss.
5. The valve has simple structure, compact structure and good sealing performance. The sealing surface and ball valve are often closed and are not easily eroded by the medium.
