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. Tee, Cross, Hex Nipple, Red. Socket M/F, Red. Hex Nipple, Square Plug, Socket Banded, Hex Cap, Red.

Construction Hoist Safety Device
Safety is one of the most important for Construction Hoist, thus the Construction Hoist Safety Device is required. SAJ safety device is a product of BQ. When a cage over-speeds the device should act cut off the power stop the cage on mast gradually. The safety device is adjusted and sealed. Do not disassemble it. The using time limit of safety device are signed on it`s nameplate. Safety device must be delivered to the factory and inspected after it reached to time limit.
Safety device board is the connected part between safety device and other structures, it can take the impact of stopping the cage. There are installed lower speed switch, upper travel limit switch and final limit switch, once the switchs touch the relevant cam the cage will act.
We also supply other spare parts for construction hoist, such as construction hoist Mast Section, Construction Hoist Anchorage Frame, Passenger Hoist Cage, Construction Hoist Overload Protector, Sliding Contact Line, Construction Hoist Motor, Construction Hoist Reducer and so on.
