The pressure relief valve consists of a main valve, a pressure relief/pressure maintaining pilot valve needle valve, a ball valve, a micro filter and a pressure gauge to form a hydraulic control takeover system.

Pneumatic butterfly valve has excellent two-way sealing function and is the best device for regulating flow, cutting off or connecting fluids on pipelines with different media such as petroleum, chemical industry, metallurgy, electric power, food, medicine, water supply and drainage, gas transportation, etc.

The fan adjustment valve changes the characteristic curve of the fan by adjusting the speed of the fan, which can keep the fan work in the area without bringing additional energy loss.

Double directional spiral gate

High temperature plug-in valve, with a maximum temperature of 450 ℃ -1100 ℃, is equipped with a special design of tracking seal on the valve plate, as well as a special casting material that is approved for the use of tertiary air ducts, making the equipment have good sealing performance, corrosion resistance, high temperature resistance, and impact resistance.

The circular gate valve is often used under the circular discharge port. The movement direction of the gate is perpendicular to the direction of the fluid. The circular gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled.

Rectangular shutter valve is a reliable device for regulating and opening and closing air, flue gas, dust gas and flammable gas. It is widely used in metallurgy, mining, building materials, chemical industry, power stations and other industrial sectors.

The main valve of the flow control valve is identical to the on/off valve, except that the driving device of the flow control valve is different. The driving device of the flow control valve is an adjustable electric actuator. Flow control valves are often used in series with pneumatic switching valves.

Manual butterfly valve is composed of a handwheel mechanism and a valve body, which has the advantages of simple structure, convenient operation, light weight, and small leakage. Manual butterfly valves are widely used for manual adjustment in industrial sectors such as metallurgy, petroleum, chemical, and power plants.
