VALVE CONSTRUCTION 2-WAY VALVES 3-WAY DIVERTING VALVES OPTIONS & ACCESSORIES
ROTARY SHAFT ASSEMBLY: The Rotary Shaft Assembly has a primary o-ring seal and a secondary, spring-loaded packing seal, providing zero leakage to the environment.

The rotary shaft rotates approximately 20° to 30° to open and close the Piston Assembly inside the valve, virtually eliminating seal wear.

PISTON ASSEMBLY: The Piston Assembly is directly connected to the Rotary Shaft Assembly allowing all valves to operate from 0 PSI up to the valve's rated pressure.

The Direct Operated Piston Assembly uses a solid piston with large clearance areas to easily accommodate dirty or viscous liquids.

The Direct Operated, Pilot Assisted Piston Assembly (shown here) uses an internal pilot orifice that assists the piston by relieving the pressure above it, thus accommodating higher pressures and/or larger pipe sizes.
SOLENOID: Explosion-proof approved for Hazardous Atmospheres. Consult the factory for listing details.

END CONNECTION: NPT, 150# ANSI Flange, 300# ANSI Flange, Socket Weld, Union, many other choices available.

VOLTAGES: See Page 5 of Catalog ER-2.0 or Solenoid Characteristics Table below (Click Here).

OPTIONS: Position Indicating Switches, Manual Override with Lock Pin, Electrical Terminal Box and others.
APPLICATION:
Clark-Cooper's Rotary Shaft Style Solenoid Valves are used to control the flow of Extremely Corrosive Fluids • Dirty Fluids • Viscous Fluids • Cryogenics • Fuel Oils • Flammable Liquids and Gases • Steam • High Temperature Liquids and Gases • Heat Transfer Liquids. The valves are used for applications where it is desirable to have the solenoid and all its magnetic components isolated from the process fluid.
FULLY ELECTRIC

FULLY ELECTRIC VALVE controls process liquids and gases without ancillary pneumatic or hydraulic systems.

  • NORMALLY CLOSED, ENERGIZE TO OPEN: Valve opens when energized and closes when de-energized.
OR
  • NORMALLY OPEN, ENERGIZE TO CLOSE: Valve closes when energized and opens when de-energized.
    EMERGENCY TRIP VALVES

    MANUALLY RESET, EMERGENCY SHUT OFF VALVE immediately stops the flow of fluid when an emergency or shutdown condition exists.

    • ELECTRICALLY TRIPPED CLOSED: Valve immediately closes upon electrical signal. MANUALLY RESET OPEN
    OR
    • TRIPS CLOSED ON LOSS OF POWER: Valve immediately closes on loss of power. MANUALLY RESET OPEN.
    OR
    • HEAT ACTUATED CLOSED: Valve immediately closes at 135°F, 165°F, 212°F, 286°F or 386°F. MANUALLY RESET OPEN.

    When the emergency condition has passed, the valve MUST BE manually reset to the open position.
    MANUALLY RESET, EMERGENCY DISCHARGE VALVE immediately releases fluid when an emergency condition exists. Used for emergency dump, deluge or purge systems.
    • ELECTRICALLY TRIPPED OPEN: Valve immediately opens upon electrical signal. MANUALLY RESET CLOSED.
    OR
    • TRIPS OPEN ON LOSS OF POWER: Valve immediately opens on loss of power. MANUALLY RESET CLOSED.
    OR
    • HEAT ACTUATED OPEN: Valve immediately opens at 135°F, 165°F, 212°F, 286°F or 386°F. MANUALLY RESET CLOSED.

    When the emergency condition has passed, the valve MUST BE manually reset to the closed position.
    APPLICATION:
    Clark-Cooper's Rotary Shaft Style, 3-Way Diverting Solenoid Valves are used to control the flow of Extremely Corrosive Fluids • Dirty Fluids • Viscous Fluids • Cryogenics • Fuel Oils • Flammable Liquids and Gases • Steam • High Temperature Liquids and Gases • Heat Transfer Liquids. The valves are used for applications where it is desirable to divert the process fluid to another location, such as a recirculation tank.
    Fully Electric Valve

    FULLY ELECTRIC DIVERTING VALVE diverts the process fluid when energized, returns to normal flow direction when de-energized.

    Emergency Trip Valves

    MANUALLY RESET, EMERGENCY DIVERTING VALVE immediately diverts flow when an emergency condition exists.

    • ELECTRICALLY TRIPPED: Valve immediately diverts flow upon electrical signal. MANUALLY RESET.
    OR
    • TRIPS ON LOSS OF POWER: Valve immediately diverts flow upon loss of power. MANUALLY RESET.
    OR
    • HEAT ACTUATED TRIP: Valve immediately diverts flow at 135°F, 165°F, 212°F, 286°F or 386°F. MANUALLY RESET OPEN.

    When the emergency condition has passed, the valve MUST BE manually reset.
    NOTE: Valve configurations vary depending on Pipe Size, End Connection, Material Selection and other factors. Consult the factory for details.

    Photo at the top of the page shows a single valve body with a tailpiece configuration.

    Diagram to the left shows a configuration using (2) 2-way valve bodies with one end capped.

    Both configurations operate in a similar manner.
    Position Indicating Switches
    • 1 or 2 switches can be mounted to the bracket
    • Mechanically Actuated
    • Heavy Duty SPDT or DPDT
    • Watertight and/or Explosion-Proof Enclosures (see Figure 1)

    Terminal Block available:

    • Mounted in a separate enclosure for easier electrical connections.
    • Mounted on the back of the bracket (see Figure 1) or other suitable location.

    Manual Override with Lock Pin allows the valve to be operated manually and locked in place. A knob is added to the lever for easier operation (see Figure 2).
    Dashpot for slow closing to reduce water hammer effect.

    Shock and Vibration construction for qualification in accordance with Military Specifications MIL-S-901 and MIL-STD-167-1.
