Groove gate valve
The groove gate valve is manufactured by introducing European high-tech rubber and valve manufacturing technology, which overcomes the defects of rubber aging and rusting. The valve has the advantages of light switch, reliable seal, good elastic memory and long service life. The products are widely used in tap water, sewage, seawater, water treatment, environmental protection, construction, fire protection, petroleum, chemical industry, electricity, food, medicine, textile, ship, energy and other industries. The industrial pipeline acts as a regulating and closing device.
Flat-bottom seat
Generally gate valves often accumulate in grooves at the bottom of valves after the water-flowing flushing pipe due to foreign materials such as cement blocks, iron chips and other debris. It is easy to cause leakage phenomenon that can not be closed tightly. The bottom of elastic seat gate valves is designed with flat bottom, which is the same as the pipeline. It is not easy to cause debris siltation and make the fluid smooth and unimpeded.
Precision Casting Valve Body
Precision casting is used for the valve body. The geometric dimension of the valve body ensures the sealing of the valve without any processing at any time.
Valve plate cladding
The valve plate is covered with high quality rubber. The European rubber vulcanization technology ensures the geometric size of the vulcanized valve plate, and the rubber and ductile iron valve plate follow firmly, which is not easy to fall off and has good elastic memory.
O-ring seal ring
Because the valve stem and cover are sealed with three O-ring seals, the friction resistance of the switch can be reduced, the leakage phenomenon can be greatly reduced, and the sealing rings can be replaced without stopping the medium flow in the pipeline.
Help students drink
Because the inner part of the valve body is coated with epoxy resin, the inner and outer surfaces of the valve plate are covered with rubber without molten iron or corrosion, which can be used for raw drinking.
Labor-saving device
DN450-600mm, can be installed additional labor-saving device, the required torque is about 1/2 of normal, only a small handwheel, under pressure, can be operated fully open or closed, the labor-saving device in each action, the valve must be fully opened before restoring the labor-saving function.
