ODE & CEME Manual Override Solenoid Valves

Manual override solenoid valves from ODE and CEME are designed for applications where control, safety, and serviceability are critical. Whether you're dealing with electrical failure, commissioning, or maintenance, these valves give you full manual control without removing the coil or depressurizing the system.

Key Features & Configurations

• Manual override options
  • Screw-type, or latch-style overrides
  • Allows valve actuation during power loss or system testing
• Valve configurations
  • 2/2 way (on/off) such as 21A31K1V25-T3 and 21A22K1V25-T3, 9399VN190SF02, 9922EN28NC77
  • 3/2 way (diverting)
  • 4/2 & 5/2 way (directional control for actuators) e.g., 512946W0B12-A
• Connection sizes
  • From 1/8" to 2"
  • Available in NPT and BSP (G thread)
  • Namur

• Body materials
  • Brass
  • Lead-free brass
  • Anodized aluminum (lightweight, pneumatic-focused)

• Seal materials
  • NBR – general-purpose air/water
  • EPDM – hot water, steam, glycol
  • Viton (FKM) – chemicals, oils, higher temperatures
  • PTFE (Teflon) – aggressive media and high purity applications

Electrical Options

• Wide voltage availability for global use:
  • 12V / 24V DC
  • 24V / 110–120V / 220–240V AC
• Latching (impulse) coils available for:
  • Low power consumption
  • Battery-operated or remote systems

Speed Control & Adjustable Flow

Many ODE and CEME valve configurations can be paired with:

• Integrated or external speed control valves
• Adjustable flow regulation
• Ideal for:
  • Pneumatic cylinder speed control
  • Gradual opening/closing to prevent water hammer
  • Precision dosing and metering systems

Applications

Manual override valves are used across residential, commercial, and industrial systems, including:

• HVAC & hydronics systems
• Compressed air and pneumatic automation
• Water treatment and filtration
• Food & beverage equipment (NSF-sensitive setups)
• Steam and hot water systems
• Fuel and chemical handling
• OEM machinery and process control panels

Why Manual Override Matters

• Emergency operation during power failure
• System testing & commissioning without energizing coils
• Maintenance efficiency — isolate and actuate valves manually
• Safety control in critical shut-off or diversion systems
