ASAHI AV Manual Valves

Diaphragm Valves When the diaphragm, which is connected via compressor to the valve stem, is pulled away from the bottom of the valve body, the fluid has a smooth, streamlined flow.
Ball Valves Ball valves open and close quickly with a quarter turn. Their name is derived from the flow-controlling ball located within the valve body.

Butterfly Valves The name of this valve comes from the wing-like action of the flow-controlling disc, which operates at a right angle to the flow.
Check Valves These self-contained, automatic valves are used to prevent flow reversal in a line.

Gate Valves These valves operate by rotating the hand-wheel. Rising stem gate valve hand-wheels move up and down at a right angle to the fluid flow. The valves inside diameter matches that of the piping used.
Feeding Valves Used in the agriculture industry as air release valves and automatic water supply valves.

Other Valves We also produce many other thermoplastic valves.
