The Cole-Parmer VapLock Pinch Valve, NC, 1/16 in ID, 12 VDC (12021-24) is a two-way normally closed solenoid-operated pinch valve supplied with 12 in of silicone tubing. It accommodates 1/16 in ID x 1/8 in OD tubing, operates from 12 VDC at 2.9 W and is rated for a maximum pressure of 15 psi (1 bar).
Key Features
- Two-way normally closed flow control, opening and closing the flexible tubing through solenoid actuation
- 1/16 in ID x 1/8 in OD tubing size, with 12 in of silicone tubing supplied already installed
- Tubing is the only wetted material, creating an unobstructed flow path without internal valve dead volume
- 15 psi maximum operating pressure, equivalent to 1 bar for the specified valve configuration
- Low 2.9 W power consumption, operating from a 12 VDC power supply with limited heat generation
- Continuous-duty solenoid operation, allowing the valve to remain fully energised indefinitely without damaging the valve or tubing
- Minimum 2 million valve cycles, providing durable repetitive opening and closing performance
- Silicone tubing rated for more than 300,000 cycles, resisting sticking even after prolonged closure
- Chemically resistant PPS and ASA/PC construction, combining a PPS plunger/seal with an ASA/polycarbonate housing
- Precisely controlled stroke and closing force, helping protect the tubing during repeated valve operation
Benefits
- Simplifies fluid-path maintenance because the tubing can be replaced without dismantling a conventional wetted valve body.
- Reduces areas where fluid can become trapped by keeping the internal flow path within the tubing itself.
- Allows particulate-containing fluids to pass through an unobstructed tubing path without conventional internal valve components in contact with the fluid.
- Supports repeated automated fluid control with continuous-duty operation and high cycle-life specifications.
- Makes cleaning and sterilisation workflows easier because the supplied silicone tubing can be removed and replaced when required.
Why Choose the Cole-Parmer VapLock Pinch Valve, NC, 1/16 in ID, 12 VDC (12021-24)?
The Cole-Parmer VapLock 12021-24 provides normally closed fluid control while keeping silicone tubing as the only wetted material, helping eliminate internal dead volume and simplify tubing changes. Its 12 VDC continuous-duty solenoid, 2.9 W power consumption and minimum 2 million valve-cycle rating suit repetitive fluid handling applications requiring compact automated control.
