Lee IMH Check Valves and Shuttle Valves | |
 | Check Valves | | | |
 The IMH Chek™ is a threadless, cartridge-style insert designed for simple, low cost installation into manifolds, and is based on the same hard seat Lee Chek® designs used in flight control systems of almost every aircraft flying today.
A robust design and 100% testing ensures consistent, long-term performance up to 28 MPa (4000 psid) and 149°C (300°F) or higher depending on specific application requirements. A high quality metal to metal seat limits leakage in the checked direction to no more than 20 sccm of air at 172 kPa (25 psi) differential. The valves are compatible with hydraulic fluids, brake fluids, fuels and oils and integral safety screen protection is available.
- Compact Design - Can be easily integrated into high volume, automated assembly lines. A cost effective alternative to in-house check or relief valve design.
- Metal to Metal Seating - Provides high reliability and long life.
- Guided Ball Design - Aligns ball with seat and provides a positive stop to prevent spring from going solid.
- Pre-Assembled - For ease in installation and handling.
- Easy to Use - Slip the check into a drilled hole and drive the pin flush
- Wide Operating Temperature Range: – 50°F to +300°F.
- Compatible with Most Fluids

Shuttle Valves
 The new IMH Shuttle Valves are miniature, economical and reliable solutions to the problem of hydraulic isolation in manifolds. Featuring a compact, non-detented, selective design, the valves are available in both 5.5 and 8 mm diameters. Designed for reliable operation, each valve is 100% performance tested for flow and leakage to ensure consistent, long-term performance.
