摘要:
A fluid control valve is configured in a manner that a first passage has at one end portion thereof a first port communication passage communicating with a first port, and at the other end portion thereof a first valve hole communication passage communicating with a valve hole, and the first port communication passage and the first valve hole communication passage communicate with each other. The resin valve body is provided with a valve seat support part which supports the valve seat and which is provided between the valve chamber, and the first port communication passage and the first valve hole communication passage. The valve seat support part has a valve seat reinforcement part, and the valve seat reinforcement part is formed so as to partially close the inside of the first passage.

摘要:
In an assembling structure of an actuator part of a chemical liquid valve, a cover is formed with a protrusion extending in a radial direction of a valve element, and a cylinder is formed with an engagement part engageable with the protrusion. A cover is placed to hold a spring in a compressed state in the cylinder and make a cap part cover an opening of the cylinder. The protrusion and the engagement part are engaged with each other to integrally connect the cylinder and the cover without separating from each other.
