摘要： A direct acting pressure reducing valve includes a valve-inlet pressure introduction port; a valve-outlet pressure output port; a main valve for opening and closing a communicating conduit; a pilot pressure chamber formed with a flexible diaphragm member; a communicating hole; a connecting rod inserted in the communicating hole; and a biasing member for biasing the flexible diaphragm member in a direction to open the main valve. An insertion portion of the connecting rod has a partly-deformed circular cross section, a distance from a deformed portion thereof to a center of an imaginary circle corresponding to the communicating hole being shorter than a radius of the imaginary circle. A non-deformed portion of the partly-deformed circular cross section guides the connecting rod along the communicating hole, while the deformed portion serves as an air passage via which the communicating conduit and the pilot pressure chamber are communicatively connected.

摘要： A pilot operated directional control valve having a diaphragm held between a passage block which has a feeding port, at least one loading port and at least one discharge port, and an opposed control block which has pilot pressure passages. The ports of the passage block open into the end face of the passage block adjacent to the control block through respective fluid passages. The pilot pressure is exerted on the diaphragm by the pilot pressure passages to control the fluid connection between the ports of the passage block. The fluid passages are located in a concentric arrangement. The diaphragm has a center valve portion with an annular valve portion therearound. The two valve portions can be independently controlled by the pilot pressure acting thereon to control the fluid connection between the two adjacent fluid passages.

摘要： Disclosed is a slow-acting ON/OFF valve which includes a valve-opening pressure chamber that makes an actuating member (which actuates a valve body that comes into contact with and moves away from a valve seat to close and open a flow passage) move in a valve-opening direction against a spring biasing force in a valve-closing direction, and supplies air to the valve-opening pressure chamber, in minute increments, via a flow rate regulation valve. In this slow-acting ON/OFF valve, the dead time from the receipt of a valve-opening signal to the commencement of a valve-opening operation is short. A manifold is provided independently of the valve-opening pressure chamber. Between the valve-opening pressure chamber and the manifold, the following three valves are provided: a pressure regulation valve which allows air to flow into the valve-opening pressure chamber from the manifold until pressure in the valve-opening pressure chamber reaches a predetermined reserve pressure and which is closed upon the pressure in the valve-opening pressure chamber reaching the reserve pressure; a flow rate regulation valve which supplies air to the valve-opening pressure chamber from the manifold, in minute increments, after the pressure in the valve-opening pressure chamber reaches the reserve pressure; and an exhaust valve which rapidly discharges air in the valve-opening pressure chamber to the manifold upon pressure in the manifold dropping below the pressure in the valve-opening pressure chamber and is thereafter closed.

摘要： A normally-closed valve having a microflow rate adjusting device includes a valve stem for opening and closing a fluid passage; a biasing device for biasing the valve stem in a direction to close the fluid passage; a piston body which is engaged in a cylinder in an air-tight manner to form a pressure chamber for moving the valve stem in a valve opening direction against the biasing device; and a stopper mechanism, provided on the cylinder, for controlling a limit of movement of the piston body in the valve opening direction. The stopper mechanism comprises a stroke adjustment member which is screw-engaged with the cylinder coaxially with the valve stem so that a position of the stroke adjustment member relative to the cylinder can be adjusted, and includes an annular tapered surface at an end of the stroke adjustment member which faces the piston body.
