摘要： Provided is a diaphragm valve that is capable of increasing its flow rate and is capable of suppressing variation among the diaphragm valves in the flow rates. In a diaphragm valve 1, a fluid that has flown into the fluid inflow channel 2a enters a fluid outflow channel 2b via through holes 22a of a seat holder 5. On a bottom surface 13 of a depression 2c of a body 2, a seat receiving surface 13a that receives a seat 4 is flush with a seat-holder receiving surface 13b that receives a seat holder 5. In the bottom surface of the depression 2c of the body 2, an annular groove 14 facing through holes 22 of the seat holder 5 is formed.

摘要： As passages forming a main gas passage, each of the passage blocks 3 has a first inverted-V passage, a first outlet passage communicating between the apex of the first inverted-V passage and an outlet of a first on-off valve. As passages forming a vent gas passage, each of the passage blocks 3 has a second inverted-V passage and a second outlet passage communicating between the apex of the second inverted-V passage and an outlet of a second on-off valve. As passages forming a first sub-gas inflow passage, each of the passage blocks has a first inlet passage leading to an inlet of the first on-off valve and a common inlet passage. As passages forming a second sub-gas inflow passage, each of the passage blocks has a second inlet passage leading to an inlet of the second on-off valve and a communication path continued to the common inlet passage.

摘要： To provide a diaphragm and a diaphragm valve which solve a problem of deterioration of air-tightness due to insufficient tightening of a bolt and damage to the diaphragm due to over-tightening of the bolt, as well as reducing variations in performance such as durability of the diaphragm and simplifying tightening work. A diaphragm is provided with a through hole having a diameter larger than a diameter through which a bolt can be fitly inserted. A bolt insertion cylinder made of metal through which the bolt can be inserted is fitted in the through hole. A height of the bolt insertion cylinder is equal to or less than a height of the through hole.

摘要： Provided is a diaphragm valve whose durability is improved by proper caulking. On a bottom surface 2d of a depression 2c of a body 2, an annular inner projection 22 having a relatively small diameter and an annular outer projection 23 having a relatively large diameter are provided. A seat 5 is made of synthetic resin and is inserted between the inner projection 22 and the outer projection 23. Both projections 22, 23 are caulked, whereby the seat 5 is prevented from coming off. The height of the inner projection 22 is less than that of the outer projection 23, and a corner 22a on the outside of the inner projection 22 has a curved surface.

摘要： Provided is a fluid drive valve, which facilitates continuation of monitoring all the time, and which allows detection of leakage of an operation fluid from an actuator even when the actuator is operating. A pressure sensor is disposed on a pressure receiving surface, inside an actuator, on which pressure of an operation fluid acts. A pressure sensor is disposed on a non-pressure receiving surface, inside the actuator, on which pressure of the operation fluid does not act. In addition, a position sensor is disposed to detect the position of a valve stem.
