<p>PURPOSE: To enable excellent mechanical reliability, easy manufacture, and low cost by forming a casing into a tubular shape made of an extruded material and providing a connector in an opening part of a housing. CONSTITUTION: A valve main body 1 is surrounded by a tubular casing 25 made of, for example, an extruded material of metal on its four faces. The center of this casing 25 is put on a rib 26 of the main body 1, and this casing 25 has four groove holes 27 in which fixing screws 28 for fixing the casing 25 on the main body 1 are stored. Moreover, it has an opening part 31 in which a connector 32 constituted by an insertion plug with screw is arranged. This connector 32 is inserted from the outside of the casing and is fixed on the casing by a screw 33. These connectors 32 have a ferrule 34, and a play in the radial direction is eliminated by an annular joint 35.</p> |
