High quality piston needle valve provider: Flow control valves are used to regulate the flow volume of passing fluid in hydraulic systems. It prevents excessive flow by limiting flow to a preselected maximum rate, regardless of changing line pressure. It is a hydraulically operated, pilot controlled, diaphragm valve. The pilot control responds to the differential pressure produced across an orifice plate installed downstream of the valve. Accurate control is assured as very small changes in the controlling differential pressure produce immediate corrective action of the main valve. Flow rate adjustments are made by turning an adjusting screw on the pilot control. SHSUOTE is the top flow conrtrol valve manufacturer in China, hydraulic flow valves provide precision flow control in 1 direction, and automatically allow unrestricted free flow in opposite direction. The valve includes an orifice plate with a holder that should be installed one to five pipe diameters downstream of the Valve. As a flow control valve supplier, we provide several orifice plate with different hole optional for each size, see the additional table for selection of orifice to guarantee accurate control of flow rate.

The pressure relief valve is a type of valve used to control or limit the pressure in a system or vessel. Exhaust over-pressurization to protect downstream equipment or control the upstream pressure of gas or liquid. It maintains a constant downstream pressure, regardless of fluctuating demand and sustains the upstream pressure to a pre-determined minimum. As a quality pressue relief valve manufacturer, we provide pressure reducing and sustaining valve for sale. They automatically perform two independent functions. The pressure reducing pilot responds to slight variations in downstream pressure and immediately repositions the main valve to maintain the desired downstream pressure. The pressure sustaining pilot is normally held open by the upstream pressure and close when the pressure drop to the set point. We are pressure relief valve supplier for over 18 years, the pressure control relief valve usually used in lower elevation pipeline to guarantee prior use of higher elevation area.
Surge Control Altitude Valve: Designed to prevent hydraulic shocks caused by sudden changes in flow rates, surge control altitude valves protect pipelines from damage and maintain stable pressure conditions. Combination Air Release/Altitude Valve: These versatile valves combine both air release and altitude control functions into one unit, providing efficient operation while eliminating excess air from pipelines. It’s important to choose the right type of altitude valve for your specific application to ensure optimal performance and longevity. Altitude valves have a variety of applications in different industries and settings. Let’s take a look at some common uses for altitude valves.
Level control valve is a type of valve that automatically responds to changes in the height of a liquid in some storage system, it can automatically open the valve to control the function of the water pipeline, applicable to industrial and mining enterprises, civil building in various kinds of water tower (pool) automatic water supply system. The liquid level control valve is designed to open fully when the liquid level reaches a preset low point, and close drip-tight when the level reaches a preset high point. The float pilot is remotely installed inside of reservoir, or integrally installed with main valve for size less than 4 inch. The high and low point can be adjusted on the spot. The max adjustable distance is 0.5m, if need more, consult factory. If you wan to buy water level control valve you can come to SHSUOTE, our valve of small, easy to install, enabling high sensitivity, small head loss without water hammer.

How do Altitude Valves Work? Altitude valves play a crucial role in maintaining water levels in storage tanks, preventing overflows and ensuring a steady supply. But how exactly do these valves work their magic? At its core, an altitude valve operates based on the principle of hydrostatic pressure. When the water level in the tank drops below a certain threshold, the valve opens to allow water from the main supply to enter and replenish it. Once the desired level is reached, the valve closes again. This process is made possible by two key components: a float mechanism and a control pilot. The float mechanism senses changes in water level inside the tank and relays this information to the control pilot. The control pilot then regulates whether or not to open or close the valve based on this input.
The valve is made of DI body and DI disc; Advanced newly design with dovetail seal design and captured by epoxy on the back, with multiple raised ring to have more contact with disc but less friction during closure; The double eccentric design provides less contact area of seal with disc, and less stress at the open position of the disc; The disc design with arch shape and thru disc can provide better flow capacity, stronger and less weight . The shaft and disc connection with tangential pin which can be exchangeable and provide rigid connection; The DN 100-500MM use flat disc, and DN 600-1200MM use arch shape disc; Epoxy coated interior and exterior; Valve design meets or exceeds EN 593; Top flange connection meets ISO 5211-1982, and F/F meets EN 558-1 series 13 & 14.
