Water Pressure Balancing Valve is used to balance water power in a system.
It specially used to measuring the change of flux of the channels.Refined Copper Valve and Soft Seal promise
the long life.Every measured point is self-sealed. When working, users chould take off the terminal-cap and
then insert the sensor through sealing. It is applicable in new system Valve. In the old system, pipe diameter is
us ually too large. When the valve is equal to the pipe,valve opening will be too small. Therefore, the new valve
which lower the Kv value, increase the valve opening, is more accuracy.
Standard export packageor according to customers' requirments
BEIJING ZLRC Enviromental Protection Equipment Co., ltd mainly foucs on FRP products and FRP related machine manufacture and export.Our main products include pipe production line, FRP tank production line,valves,water meters and other industrial hardware and so on.
(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. ZLRC 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, ZLRC 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.
