The IDEX Nonmetallic Inlet Check Valve, 0.04 in Bore, 1/4-28 Female to Male Flat Bottom (CV-3322; Cole-Parmer item 02015-91) is a metal-free inline valve designed to prevent reverse flow in laboratory fluid pathways. It combines a 1 psi (0.07 bar) cracking pressure with a 2000 psi (138 bar) maximum pressure rating and a low 49 µL swept volume.
Key Features
- One-direction inlet valve operation, helping prevent fluid from flowing backwards into sensitive upstream equipment
- Low 1 psi cracking pressure, equivalent to 0.07 bar
- High reverse-pressure capability, with a maximum pressure rating of 2000 psi (138 bar)
- Low 49 µL swept volume, supporting applications where internal flow-path volume is important
- 0.040 in through-hole, equivalent to approximately 1.0 mm
- Female 1/4-28 flat-bottom inlet port, providing the specified upstream connection
- Male 1/4-28 flat-bottom outlet port, providing the corresponding downstream connection
- Metal-free wetted construction, using PEEK and perfluoroelastomer materials
- Compact inline body, measuring approximately 0.62 in in diameter and 0.99 in in length
Note: The cracking pressure may initially be higher than the stated value when the valve is first used or after an extended period of inactivity.
Benefits
- Protects upstream components by limiting fluid movement to the intended direction.
- Supports biological samples and corrosive fluids through its metal-free wetted materials.
- Helps preserve low-volume fluid pathways through its compact internal swept volume.
- Provides chemical resistance for demanding laboratory fluid-handling applications.
- Connects directly into systems using compatible 1/4-28 flat-bottom fittings.
