The Cole-Parmer VapLock NO Pinch Valve, 1/32 in, 12 VDC (12021-33) is a two-way normally open solenoid valve that controls fluid flow by pinching the supplied silicone tubing. Its unobstructed flow path minimises pressure drop and leaves the tubing as the only wetted component, eliminating internal valve dead volume. This model operates at 12 VDC and 2.9 W, with a maximum pressure rating of 15 psi (1 bar).
Key Features
- Two-way normally open operation, allowing flow through the tubing until the solenoid is energised
- 1/32 in ID silicone tubing, with a 3/32 in outside diameter for the specified valve configuration
- Supplied with 12 in of tubing, installed and ready for integration into the fluid path
- Low 2.9 W power consumption, supporting continuous operation with minimal heat generation
- 12 VDC electrical operation, matching the specified solenoid power requirement
- Maximum pressure of 15 psi, equivalent to 1 bar
- Tubing-only wetted flow path, eliminating dead volume within the valve mechanism
- Unobstructed internal flow, minimising pressure drop and helping resist damage from particulates
- Continuous-duty solenoid design, capable of remaining fully energised indefinitely without damaging the valve or tubing
- High-cycle durability, with a minimum valve life of two million open-and-close cycles and tubing rated above 300,000 cycles
- Chemically resistant construction, using a PPS plunger and ASA/polycarbonate housing
- Precisely set stroke and closing force, helping protect the tubing and extend valve service life
Benefits
- Allows tubing to be changed quickly without dismantling or cleaning an internal fluid pathway.
- Keeps the process fluid contained within replaceable tubing as the valve opens and closes.
- Maintains an unobstructed flow path that minimises pressure loss and accommodates fluids containing particulates.
- Supports extended operating periods through continuous-duty construction and low power consumption.
- Reduces routine replacement requirements through high valve and tubing cycle-life ratings.
- Simplifies sterilisation by allowing the wetted silicone tubing to be removed and replaced when required.
