They are normally equipped with a 3-way or 4-way solenoid pilot that controls the opening or closing of the main valve using operating pressure. Air operated Solenoid Valve; This solenoid valve type has two basic functional units. modular valve systems fitted with a complete range of functions and state-of-the-art bus technology. Let the application dictate the requirements - we will supply the right technology. Aside from technology based on conventional switching valves, we also provide optimal solutions featuring electro-pneumatic pressure regulator technology. Introduces the functions of the basic parts common to most types of valves. Provides information on applications of many types of valves. Types of valves covered include gate valves, globe valves, ball valves, plug valves, diaphragm valves, reducing valves, pinch valves, butterfly valves, needle valves, check valves, and safety/relief valves. Ball type check valve In Fig. 1.2, a light spring holds the ball against the valve seat. Flow coming into the inlet pushes the ball off the seat against the light force of the spring and continues to the outlet. A very low pressure is required to hold the valve open in this direction. Common types of directional control valves include 2/2, 3/2, 5/2, etc. The first number represents the number of ports; the second number represents the number of positions. A directional control valve that has two ports and five positions can be represented by the drawing in Fig. 8, as well as its own unique pneumatic symbol. Three-way valves can be used as a remote air pilot for larger valves. Panel mounted 3-way control valve Power Valve 2 OUT 3 EX 1 IN 2 OUT 3 EX COOLING AIR 1 IN N.O. 3-way Actuated (Cooling air held off) Note:A normally open 2-way poppet valve can also be used in place of the normally open 3-way above. N.O. 3-way unactuated (Upon loss of pilot the flow rate and pressure. To select the correct valve to fulfill these functions properly, an outline of the different types of valves and their features is given below. Butterfly valve Butterfly valve and globe valve Butterfly valve and ball valve Butterfly valve and gate valve Check valve Gate valve Globe valve Ball valve Valve shaped like a For example, a 2/2-way pneumatic valve is a valve that has two switching positions and two ports. A 3/2-way valve is a two position valve with three ports. By extension, a 4/2-way valve represents a valve that has two switching positions and four ports; a 5/2-way valve has two switching positions and five ports. Here is a summary of the main types of pneumatic valves in use today: Spring Offset Valve. This type of pneumatic valve classification refers to the manner in which air-flow direction is switched. For example, in a two-way directional valve, the valve either opens (air-flow is enabled) or closes (air-flow is prevented). In order for each port Catalog excerpts. Selection guide Model no.
