Since the flow passage of the ball valve is the same cylindrical shape as that of the pipe, the flow is smooth, and it is a valve with extremely small fluid resistance among various valves. (Full bore type ball valve)

The ball valve is suitable for automation because it is fully opened and fully closed with a 90° rotation. We have standardized actuators for both pneumatic type and electric type, and we have made an appropriate and efficient response to the nominal valve diameter, operating conditions, etc.

The valve has a plastic sheet on the primary side (inlet) and secondary side (outlet) of the fluid around the ball. When closing, the ball is pushed against the fluid pressure, and the ball acts as a sealing force against the secondary side sheet. (Floating type ball valve)

Ball valves are nearly spherical in shape as compared with general sluice valves and ball valves, and their height, weight and compactness compared with those of the same nominal diameter make them also small in stress applied to piping, making them suitable for mounting in limited narrow spaces.

For general gate valves and ball valves, the handle must be rotated back and forth 10 times to fully close the valve from fully open, but the ball valve only makes a quarter turn (90°).

The structure of the ball valve is relatively simple, and it is easy to disassemble, assemble and maintain because of the small number of parts.

We provide a variety of ball valves with standard specifications to meet the diverse use conditions of our customers.

It is necessary to carefully examine the conditions of the target fluid, such as fluid, pressure, and temperature, before selecting the fluid.

Each valve has a working range of pressure and temperature. Be sure to confirm the conditions of the fluid before selecting.

• The standard soft seat of our ball valves uses PTFE based seat material, which limits the operating pressures and temperatures. For high-pressure, high-temperature fluids, select the “Metaball” or “Carbotite” series.
• We recommend PVC ball valves made of stainless steel and high-pressure-resistant resin for fluids with flow rate, differential pressure, and piping conditions, ductile iron ball valves for high-pressure gas and steam fluids, and cast ball valves for petrochemical plants.
• Select a 3-way ball valve for the line for changing the flow path or for shunting and fluid mixing.
