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.

 |
| IN-HOUSE CHECK VALVE | LEE CHEK® | |
| (Find the parts, coin the seat, assemble the parts, stake in place, test) | (Pre-assembled, auto-insertable, 100% tested) |
Why fuss with the in-house approach when the Lee High-Performance Check Valve installs in less time, works more reliably, lasts longer and costs less.
Lee Chek® features include:
- Quick, automated installation
- 100% performance tested
- 4000 psid working pressure
- All stainless steel construction
- 5.5mm and 8.0mm diameters
- Cracking pressure from 0 to 150 psid
Check Valves in Plastic Fittings
  |
Check valves can now be supplied pre-installed in plastic fittings for disposable medical applications (eg angioplasty). Typically, two 2.5 or 5.5mm diameter check valves are used, one to provide an inlet check valve function and the other to provide a pressure relief function to prevent over-pressurisation of the angiplasty balloon. |

CCPI Check Valves (5.5 and 8mm diameter)
The Lee CCPI Series Press-In Chek is a miniature cartridge-style check valve specifically designed for installation into plastics. The unique barbed design provides easy installation, ensures retention and prevents any by-pass leakage around the valve. A robust design and 100% performance testing ensures consistent long term performance.

832 Series Side Exit Check Valve
 |
8mm diameter high flow side exit check valve. The IMH 832 Series Side Exit Check Valve provides the lowest pressure loss of any valve this size. At only 8 mm in diameter, this valve features a side exit design which will flow in excess of 6 usgpm of water at 100 psid. |
