GOST BUTTERFLY VALVE
Gost butterfly valves are Non rising stem, spring loaded check valves with cast iron bodies and pressure balancing discs.The metal to metal disc cannot be disassembled until the valve reaches the required position of the six lugs machined on the disc. The disc contacts an O-ring packing to provide a seal at low operating pressure.
Product introduction:
Gost butterfly valves are Non rising stem, spring loaded check valves with cast iron bodies and pressure balancing discs. The metal to metal disc cannot be disassembled until the valve reaches the required position of the six lugs machined on the disc. The disc contacts an O-ring packing to provide a seal at low operating pressure. Gost butterfly valve is used to control the flow of liquid or gas, and the media include water, oil, steam, air, natural gas and other media. One or more seats and seals are used to hold the disc shape in place. When the medium pressure outside the seat ring increases, it can be opened by raising the angle of the disc to allow more flow to pass.
Gost butterfly valve is a light-weight butterfly valve with large lifting capacity, good self-cleaning performance and easy wear. It has large opening, can maintain high flow rate, good sealing performance and low power consumption. Gost butterfly valve is a double disc, single seat valve. The valve body has two independent concentric disc assemblies, which are straight from the spindle end of the flow area; The seat ring is located in the center of one of the discs. The balance ring can be arranged on either side of the seat ring with an angle of ± 5 to 90 ° relative to it.
Product advantages:
butterfly valve is a stop valve or angle valve, in which one disc is installed concentric with the valve stem, and almost covers the port opening when closing. The disc ("Butterfly") opens and closes on a hinge, or in some cases slides back and forth on the track of the pipe. The word "Butterfly" was first used to describe this type of valve because the shape of the disc is similar to the body parts of insects.
Butterfly valve is an automatically operated valve, which uses the check principle. Its working mode is to use a mechanism to rotate 90 degrees, so the fluid cannot pass freely in one direction, and there is no restriction when opening and closing the valve in the other direction.
Product design:
Gost butterfly valve is designed to be the most convenient solution for the pipeline under any condition, and is used by the management agencies of each member. Compared with other types of butterfly valves, it has higher reliability, durability, low noise and better sealing performance. The main features of gost butterfly valve are: minimum height -100 mm; Compact structure; It can be installed on both sides of the pipeline; Balanced structure (non lubricated).
Gost butterfly valve is a high-quality valve specially designed for the transportation industry. The special design makes these valves especially suitable for any type of hydraulic oil, as well as most common gases, such as air and steam. They can also be used with other chemicals that do not corrode valve materials. The internal structure of each valve is equipped with a large number of oil-free ball bearings, which can work perfectly after long-term operation.
