GATE VALVE MANUFACTURER IN INDIA
Specialityvalve is one of the leading gate valve manufacturer in India. The product is used in a variety of industries, including the chemical, petrochemical, and power generation industries, as well as the pulp and paper and oil and gas refining industries. There is a wide range of gate valves available. Gate valves are commonly manufactured in India.
We offer a diverse range of gate valves to meet the diverse needs of our valued clients. To eliminate the possibility of any flaw, our gate valves are thoroughly tested against a set of quality parameters.
We have been providing high-quality gate valves to our customers for many years. We manufacture various gate valves for our customers based on their specific needs, such as rising stem gate valves, non-rising stem gate valves, bellow sealed gate valves, pressure seal gate valves, forged gate valves, cryogenic gate valves, and industrial valves. Valve dimensions, sizes, and classes can be customized to meet the needs of the customer.
BODY AND BONNET
The body is built with uniform sections and generous radius fillets to prevent stress on all sides. The body has a straight through port with no recesses except between the seats to achieve the least amount of turbulence, erosion, and resistance to flow. The bolted bonnet is equipped with a back seat ring to guide the stem and provide a back seat when the valve is fully open. The Yoke is a cast component of the bonnet.
Valve body-bonnet joints for ASME class 150 valves are octagonal in shape and flat on one side. There are male and female bonnet joints in ASME class 300 and 600 valves. Customers can choose from a variety of gasket materials.
WEDGE
Valve body-bonnet joints for ASME class 150 valves are octagonal in shape and flat on one side. There are male and female bonnet joints in ASME class 300 and 600 valves. Customers can choose from a variety of gasket materials.
SEAT RING
Seal welded seat rings are intended to have a low pressure drop and to resist corrosion. Also eliminated is leakage through the path between the seat rings and the body.
STEM
The T head on the stem engages with the T-slot in the wedge. Its surface is precisely machined and ground to reduce friction, thereby extending the life of the stem packing and ensuring perfect tightness. The stem also includes a back seat shoulder to match the back seat ring in the bonnet.
YOKE
The yokes are machined to fit the cap exactly if they are not integrated with the bonnet and make them excellent for rear seat covers.
YOKE SLEEVE
The jumper features the lengthy thread to provide the stem with precise alignment. In ASME class 150-300, and 6’ or higher in ASME class 600 the yoke sleeve is installed on push rods for simple operation for 14 or above.
GLAND
The gland are autonomous and have a cylindrical shape of a flange of glands. It is not pressed by the shoulder on the glans and pushed into the filler box.
STUFFING BOX
The box is meant to enhance the life of packaging rings of class 300, with a latern ring between the packaging rings above the valves.
Applications: They are used in industries like Chemical, Petrochemical, Power Generation, Pulp and paper, Oil and Gas refining.
Advantages of Gate valve:
- Gate valves have very low friction loss;
2.They can be used in both directions in the circuit;
- They provide laminar flow with minimal pressure loss;
- and they help to save energy and lower total cost of ownership.
- Gate valves have a low pressure drop when fully opened and sealed.
