Our Products
Our Complete range of products are Ball Valves, CARBON STEEL AND STAINLESS STEEL BALL VALVES, Damper Valves and Pulp Valves.
AMCO Ball Valves are Manufactured with Full Port/Regular Port constructions. Where the application requires minimal pressure drop, the user is advised to opt for Full port construction. When a Ball Valve is chosen to replace a Gate Valve, the obvious choice is a Full Port Ball Valve. But when pressure drops are acceptable or if regulating valves such as globe valves are replaced on the line with Ball valves, Regular Port Design would be quite adequate. Full port and Regular Port Ball valves, are identical to each other with regards to the dimensions.
The AIVmodel Butterfly dampers, offered by Amco Industrial Valves, India are essentially seatless Butterfly valves intended for low pressure gas lines and air lines. The lightweight construction with the narrow wafer body enables easy fitment of these valves in ducts, manifolds and exhaust lines without additional support or strengthening of pipe lines.
These valves are primarily intended for low pressure large volume gas / air flow control applications. The absence of seat substantially reduces the valve operating torque requirements and makes the valve very effective for flow control / regulation duties. Thisis an ideal choice for furnace air flow and combustion control applications.
Even though the body is designed for a maximum pressure of 2.5 bar the maximum shut off pressure is limited to 0.5 bar only .The disc flap is held in position by a stub shaft with an axial locking arrangement provided on the top shaft. The top shaft sealing is through stuffing box type gland sealing arrangement, which is field adjustable.
