Are you looking for small and light weight Check Valves?
Denisdeploeg offers a wide variety of miniature, pre-tested cartridge check valves that offer proven reliability and performance. With almost one million valves successfully in service, some for over 20 years, Lee check valves set the standard for small size, light weight and proven reliability. Five types of miniature check valves are available:
- Axial Flow Check Valves
- Side Exit Check Valves
- Zero Leak Check Valves
- Pilot Operated Check Valves
- Field Serviceable Check Valves
AXIAL FLOW CHECK VALVES
The 093 Lee Chek® is an ultra miniature, precision, side-exit check valve. This 0.093″ diameter check valve is based on the same field-proven technology as the 0.187″ diameter side exit Lee Chek®.
NACE compliant versions of the High Pressure Cheks are a perfect solution for applications in the harsh environments found in the oil tool industry. Available in 0.125, 0.187, 0.250, 0.375 and 0.500 inch diameters, these valves are designed to check pressures up to 15,000 psid.
The Lee Company’s new family of HFS (High Flow Slotted) check valves offered by DenisDePloeg offers both high flow and high pressure capability in a compact package. Offered in a choice of either axial or side-exit flow, HFS Lee Check Valves are shorter in length than other high-pressure designs.
Poppet-style, high flow-gain check valves that are wide open at 15 psid, and offer the lowest Lohm rate (highest flow). Available in 0.187, 0.250, 0.375 and 0.500 inch diameters, in both forward and reverse flow directions to meet almost any space requirement. Versions with a 440C CRES poppet are available for each size to accommodate harsh duty applications.
Lee Hi-Q Chek valves offer the greatest feasible flow capacity for valve cartridges between 1/2 and 1 inch in diameter. The valves feature a unique cage and poppet assembly that maximizes flow capacity at an effectively low cost. A robust design and 100% performance testing ensures consistent, long term performance in 4000 psi systems.
Poppet-style check valves for system pressures up to 8000 psi. Available in six sizes, from 0.125 inch diameter, up through 0.500 inch diameter.
SIDE EXIT CHECK VALVES
0.093, 0.187 and a 0.343 inch diameter check valves with convenient side exit porting and enhanced silt resistance. The 0.093 inch diameter is available unscreened, with forward flow only for 4000 psi systems. The 0.187 inch diameter is available screened and unscreened, with forward flow only for 4000 psi systems. The 0.343 inch diameter is available unscreened, with reverse flow only for 5000 psi systems.
The Lee Company’s new family of HFS (High Flow Slotted) check valves offered by DenisDePloeg offers both high flow and high pressure capability in a compact package. Offered in a choice of either axial or side-exit flow, HFS Lee Check Valves are shorter in length than other high-pressure designs.
ZERO LEAK CHECK VALVES
The 375 Zero Leak Chek Valve is the latest addition to our field proven, miniature zero leak check valve family. Weighing only 11 grams, the .375 inch diameter zero leak check valve is capable of flowing 1.9 GPM at 25 psid.
The 500 Zero Leak Chek Valve is an addition to our field proven, miniature zero leak check valve family. Weighing only 24 grams, the .500 inch diameter zero leak check valve is capable of flowing 3.5 GPM at 25 psid.
PILOT OPERATED CHECK VALVES
The High Pressure 250 Pilot Operated Chek is the latest addition to Lee’s line of miniature check valves. This valve acts like a normal check valve until pressure is applied to the pilot port, which then allows flow in the direction that would normally be blocked.
The High Pressure 375 Pilot Operated Chek is the latest addition to Lee’s line of miniature check valves. This valve acts like a normal check valve until pressure is applied to the pilot port, which then allows flow in the direction that would normally be blocked.
The High Pressure 500 Pilot Operated Chek is the latest addition to Lee’s line of miniature check valves. This valve acts like a normal check valve until pressure is applied to the pilot port, which then allows flow in the direction that would normally be blocked.
Field servicable check valves
DenisDePloeg now offers Power Generation Chek® Valves by The Lee Company for use in purge air, water injection and liquid fuel applications. The valves are field serviceable, allowing the user to disassemble and service the valve using a rebuild kit.
