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.
GV-Resilient seated gate valve is a soft seal disc which is fully encapsulated with rubber. The valve is designed with new technology for light operating, no clogging and no corrosion, good resilient memory & long service life. It can be used extensively in all kinds of water supply & sewage, fire-fighting and function as a shut-off or regulating valve. Features: Newly advanced design, less operation torgue & abrasion resistance; Body & Cover are made of high grade Ductile Iron; Disc is designed with an abrasion resistant nylon guide which can help less opening or closing torgue and smooth during operation; Forged stem provide stronger stem operation and less moving parts; Disc is covered by high-grade rubber which complies with drinking water; High-tech rubber curing with precise geometry dimensions, more resilient & strong adhesive to ductile casting; The 3 O-ring stem seals are designed to prevent stem leakage. and provide replacement of the O-ring without disassambling of valve from mainline pipes; Both inside & outside are coated with epoxy resin powder; Manufacturing standard meets BS EN 1074, BS 5163, BS EN 1171; F/F (Face to Face) meets the following standard: BS EN558-1.

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.
FBGD is a double eccentric flange butterfly valve, with soft seal on the body, it has the lowest operational torque, much less wearing, the dovetail seal design has been proven over half century service with reliability. Triple offset butterfly valve is designed according to API609, it provides bi-directional sealing with metal seat. No seat/disc contact in the open or intermediate position to reduce the operation torque, allowing for smaller actuators. And it has been tested to API607, available for a broad of applications.
