Rotary Shaft Style Solenoid Valves (ER Series)

Valve Construction

rotary shaft valve

    The Solenoid (A) is completely isolated from the process fluid, allowing the valve to easily handle exetremely corrosive or high temperature fluids.
  • Continuous Duty, Encapsulated Coil with Class H Insulation
  • NEMA 4X - Water Tight Corrosion Resistant Enclosure
  • Certified Explosion Proof Enclosure for Hazardous Atmospheres

    • The Plunger (B) is Teflon© coated to provid superion corrosion restistance.
    The External Lever (C) provides visual position indication and manual overide.

Basic Operation:

When the Solenoid (A) is energized the Plunger (B) pulls the External Lever (C) upwards. The lever rotates the Rotary Shaft, which penetrates the valve's pressure boundary, to open or close the Piston Assembly

Direct Operated, Pilot Assisted Piston Assembly

    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.
    OPTIONS: Position Indicating Switches, Manual Override with Lock Pin, Electrical Terminal Box and others.

2-Way Valves

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


Valve shown is a 4 inch Full Port 316 Stainless Steel, 150# ANSI Flanged fully electric valve.
Type: Normally Closed, Energize to Open
Options:
  • (2) SPDT Position Indicating Switches
  • Terminal Box mounted on back of bracket

    • 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


    Emergency Shut-Off Valve:
    Electrically tripped closed, Manual Reset open
    (Shown latched open)

    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.

    Emergency Discharge Valve


    Emergency Discharge Valve: Electrically Tripped Open, Manually Reset Closed.
    (Shown Tripped Open)
    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.

    3-Way Diverting Valves

    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


    Emergency Diverting Valve Trips on Loss of Power
    Options:
  • 316 SS Union Enc Connections
  • (2) SPDT Position Indicating Switches
  • Manual Override With Lock Pin
    • (Shown in Tripped Position)

    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
