Above data just for your reference,all products are designed based on different working conditions,requests and produced after you confirmed our production drawing.
Welcome to contact to me or visit our factory to discuss with us about any requests.
Our products includes full range of valves, flanges, casting fittings and other industrial hardware upon your request.
(1) Ball Valve is not only own with the functions of opening quickly, easy to maintain, good sealing but also safety fire-safe and Antistatic designs. Lung Yun manufactures designs various kinds of ball valves for one-piece, two-piece, three-piece, thread end, socket weld end, butt weld end, flange type, full port, reduce port. The selection of ball valve material includes stainless steel, carbon steel, and cast iron. The working pressure from 1000 psi to 6000 psi application of you chose. Designs of different sealing are as client’s requirement. Chose the suitable ball valve to use in piping system, Lung Yun is the best supplier.
(2) Gate valve is to ensure a straight line flow of a liquid when valve is fully open. The gate valve is not apply to regulate flow . Gate Valve is not necessary to open frequently ,and it maintain the valve on position of wide open or closed.
(3) Globe valve is different from ball valve, is a type of valve used for regulating flow in a pipeline, consisting of a movable plug and a ring seat in a generally spherical body. The flow direction from bottom to top is important when installing the valves.
(4) Needle valve is having a small seat ring and a pin-shaped, it allows precise regulation of flow rate. Needle valves are not only usually used in flow metering applications but used in low flow rate must be maintained for some time.
(5) Pressure reducing regulators automatically cuts off the flow of a liquid or gas at a certain pressure. Gas pressure regulators are used to regulate the gas pressure and are not appropriate for measuring flow rates. Pressure reducing regulators are used to usable pressure for various applications.
(6) Butterfly valve is used for isolating or regulating flow and its function allows for quick shut off. There are many different kinds of butterfly valves, each adapted for different pressures and different usage in the industry.
(7) Flange is one part of pipeline system that has used for inside or outside the pipe. There are many types of flanged pipes used in all aspects of plumbing. Flange is like as a communication bridge to connects the pipe or pipe fitting achievements a completely system necessary. The Flange is a necessary role of connection piping.
(8) Pipe fittings is for installing or repairing piping or tubing systems that includes Elbow degree 90, Street Elbow, Red Elbow, Elbow degree 45, Street Elbow degree 45, V Type Tee, Tee, Red.
