blind plate valve

▷The blind valve is excellent for high pressure/extreme temperature applications ▷The blind valve incorporates a tough, simple design that provides long lasting service life with minimal maintenance requirements. ▷The spectacle plate system on all line blind valves provide a positive, visual indication of the valve's open or closed status. ▷The line blind valve's gasket materials are available for most fluids and for temperatures up to 800° F. ▷The line blind valves are ideal for positive shut-off and offer absolute assurance of no downstream leakage even in both harsh petroleum and industrial applications.

1.Simplified design, ruggedly and dependably built, easy to operate and economical to maintain – are the principal advantages of the zero leakage blind valve. The blind valve will render an absolute tight shut-off in blast furnace, basic oxygen, open hearth or other gas mains. The blind valve is designed for vertical operation in a horizontal main – with rollers and other daptations provided for horizontal operation in a vertical main. 2.When in the closed position, a definite separation on each side of the goggle plate is assured – to prevent leakage of gas from one side of the blind plate to the other. Should leakage occur between the blind plate and the clamping or stationary frames (due to improper clamping, for example), leakage will be admitted to the atmosphere and not around the blin plate to the depressurized side of the valve.

1.With its superior performance, the pneumatic sector blind valve provides a safe and reliable isolation device for the automatic control of toxic, hazardous and flammable gas pipelines in metallurgy, chemical, environmental protection and other industries. 2.The pneumatic blind valve can be controlled remotely by a single unit, or by multiple units connected to the network, and can also be operated manually by the valve itself under abnormal conditions.

1.The compression transmission mechanism adopts ring gear, gear, trapezoidal thread, and screw pair to simultaneously compress in both directions. 2.The starting torque is small, the thread pair has good self-locking performance, and the valve is sealed reliably. Plate movement adopts pin gear transmission mechanism, which is not easy to accumulate. 3.Explosion-proof control cabinet can be configured to implement on-site control and remote connection control with PLC system, with a design distance of more than 10 meters.

High temperature resistance, good sealing performance, convenient replacement and long service life. Prompt action to cut off gas performance is absolutely reliable. Used in industrial and mining enterprises,municipal,environmental protection and other industries in teh gas medium，pipeline system,especially for hazardous, toxic,flammable gas asolute cut end of the pipe is also suitable as blind to shorten the repair time or the easy connection of new piping system.

▷The google valve is a reliable isolation device in gas medium pipelines, suitable for gas, gas and powder conveying pipelines in metallurgy, chemical industry, machinery, energy and municipal engineering systems。 ▷The google valve is a closed design structure, the valve body adopts a fully enclosed shell, and the gas in the pipeline during operation does not leak, avoiding environmental pollution, and has good resistance to external pipeline forces. ▷The electric device is installed on the outside for maintenance and inspection, and the safety performance of personnel close operation is high.

1.The electric blind valve is used to positively isolate downstream media flow. 2.Positive pipeline close/off is vital in many piping systems to assure safety of personnel working on downstream equipment, particularly when flammable, toxic liquids or gases could seep past a closure. A electric blind valve is mandatory to comply with certain plant safety regulations when visible proof of shut/off is necessary. 3.The blind valve will render an absolute tight shut-off in blast furnace, basic oxygen, open hearth or other gas mains applications. It is designed for vertical operation in a horizontal main - or with roller support and other adaptations for horizontal operation in a vertical main.

▷Stainless steel ring provided in valve body to prevent dust from entering expansion joint ▷Simplified design permits one man operation ▷Installation in a horizontal or vertical main ▷Goggle plate counterbalanced for ease of operation ▷Self-supporting – sufficient column strength is contained within valve structure, eliminating the need for additional support from ground ▷Self-contained alloy expansion join – face-to-face dimension never changes ▷Shipped completely assembled – ready for installation
