1 Solenoid Valves The solenoid is an electromagnetic part of a valve, comprised of a coil, coretube, core and enclosure. ASCO Redhat brand offers the worlds largest selection of 2-, 3- and 4-way solenoid valves, designed to handle the most demanding fluid control applications. 2-Way - One inlet and one outlet, and are used to permit and shut off fluid flow. The two types of operations are Normally Closed and Normally Open. 3-Way - These valves have three pipe connections and two orifices. When one orifice is open, the other is closed and vice versa. They re commonly used to alternately apply pressure to an exhaust pressure from a valve actuator or a single acting cylinder. These valves can be normally closed, normally open or universal. 4-Way - These valves have four or five pipe connections, commonly called ports. One pressure inlet, two cylinder ports providing pressure to the double acting cylinder or actuator and one or two outlets to exhaust pressure from the cylinders. They have three types of construction, single solenoid, dual solenoid or single air operator. Direct Mount - These Series are standard 3 way and 4 way solenoid valves whose NPT pipe connections and mounting configurations have been replaced by NAMUR mounting configuration. This allows each valve to be mounted directly to an actuator without the use of hard piping or tubing. Dust Collector - These series are high-flow fast-opening 2 way valves, pilot valves, pilot valve enclosures and bulkhead fittings that have been specially designed for use in dust collector systems. Group Mounted - These series are 2 way, 3 way and 4 way 2-position valves that are designed for gang mounting into different quantities of valves. Any combination of normally closed, normally open or universal valves may be grouped together. Isolation - Isolation valves incorporate a diaphragm that shields the fluid flowing through the valve from the internal solenoid components making them ideal for handling corrosive or high purity fluids. These valves are available with in-line porting or manifold constructions and in a wide variety of inert materials. Manual Reset - These series are standard 2 way, 3 way and 4 way 2-position valves that use a manual reset assembly in replacement of the solenoid. They are designed to prevent inadvertent valve startup in their designed failure modes. These series are available in no voltage release, electrically tripped, and free handle constructions as well as latched open or latched closed for 2 way valves. Medical/Analytical - Micro-Miniature General Service, Isolation, and Pinch valves for the reliable control of fluids and gases in medical equipment and analytical instrumentation. Pinch - Pinch valves are designed to control the flow of fluid by locating soft tubing in a mechanism that pinches the tubing to block flow and releases to allow flow. Pinch valves are suitable for corrosive fluids, high purity applications, or fluids with particulate. S Series - ASCO commercial application solenoid valves. Developed and engineered with ASCO s global resources. ASCO S is a compact solution for 2-way, 3-way, and steam valve applications and can operate in 15 to 125 F ambient temperature locations. This solution includes DIN connection for easy wiring, compact brass bodies and encapsulated coils. Options include 15" leads, alternate elastomers, manual operators, and mounting brackets. Options/Accessories - ASCO offers a wide variety of accessories and optional features to meet your specific application requirements.

2 Micro-Miniature Solenoid Valves Miniature General Service, Isolation, and Pinch valves for the reliable control of fluids and gases in medical equipment, analytical instrumentation, and industrial applications. General Service These micro-miniature valves are ideal for applications where small size, long life, and low power consumption are a must. They are suitable for the control of non-corrosive liquids and gases and are available as in-line or manifold mount constructions. Isolation Isolation valves incorporate a diaphragm that shields the fluid flowing through the valve from the internal solenoid components making them ideal for handling corrosive or high purity fluids. These valves are available with in-line porting or manifold constructions and in a wide variety of inert materials. Pinch Valves Pinch valves are designed to control the flow of fluid by locating soft tubing in a mechanism that pinches the tubing to block flow and releases to allow flow. Pinch valves are suitable for corrosive fluids, high purity applications, or fluids with particulate.

3 Position Indicators Valve Monitoring Systems (VMS) provide valve automation solutions for quarter turn and linear actuator applications. VR Series Bracket mounted for quarter turn actuators. NR Series Direct NAMUR mount for quarter turn actuators. Process Control Pilot Valves Valves designed for pneumatic actuation. 3-Way Valves Valves for use with spring return actuators. Pipe Connection: 1/8 through 1 threaded connections. NAMUR: Padmount valves to the NAMUR standards. 4-Way Valves Valves used with non spring return actuators. Pipe Connection: 1/8 through 1 threaded connections. NAMUR: Padmount valves to the NAMUR standards. Manual Reset Valves Primary application is to serve as a mechanically operated solenoid controlled devices on safety related and key systems. For safety related systems specially constructed units designed to trip due to loss of pneumatics or electrical power are available. Redundant Control Systems Redundant Control Systems (RCS) redundant pilot valve systems for use in a safety instrumented system or critical control applications.

4 Process Automation & Bus Communication Field Bus Protocols have been designed into ASCO Solenoid Valves, Position Indicators and Valve Islands. Valve Monitoring Systems ASCO s valve monitoring systems are a line of position indicators for linear and quarter-turn applications. This is a key component for automating your process valve package. The VMS line can easily communicate as a node over a fieldbus network. Solenoid Pilot Valves ASCO s line of solenoid pilot valves are use for piloting air into a process valve actuator. There is a wide variety of 3 and 4-way valves available for your valve automation package. All of our pilot valves can be used with or without a position indicator to automate your valve package by use of a fieldbus network.
