Three-way valve for e.g. viscous liquid, has elastic membrane that swells when it comes in contact with liquid, pressing core of valve body and ensuring optimum watertight property even when valve is used at high temperatures

摘要

The valve has a valve body provided with a core which has an elastic membrane in its interior. The elastic membrane swells when it comes in contact with liquid, pressing the core of the valve body and ensuring optimum watertight property without performing any flight and without blocking the operation of the valve even when the valve is used at high temperatures.
