摘要： A pinch valve free of outflow of fluid at the inside of a tubing to the outside of the pinch valve even if the tubing ruptures. The pinch valve 1 comprises a valve part 2, a tubing 3 inside of which a flow path is formed and accommodated in the valve part 2, a pressing part 4 pressing the tubing 3 or releasing the pressing to cause the tubing 3 to deform and open and close the flow path, and a drive part 5 driving the pressing part 4, the pinch valve further comprising a seal part sealing a fluid connection between a space near an outside surface of the tubing 3 and an outside of the pinch valve 1.

摘要： An eccentric butterfly valve includes a valve body formed therein with an internal flow passage extending in a direction of the flow passage axis, a valve member supported by the valve body through valve stems to be rotatable about a rotation axis perpendicular to the flow passage axis, and a seat ring attached to an inner periphery of the internal flow passage. The valve stems include a first valve stem and a second valve stem. The valve body is formed therein with a stem through-hole through which the first valve stem is inserted and a stem bottomed-hole supporting the second valve stem. The valve member is provided with a fitting hole and an engagement groove. A fitting portion provided at the first valve stem is fitted into the fitting hole and an engagement portion provided at the second valve stem is inserted into the engagement groove.
