Introduction
Kepner Products Company, established in 1948, specializes in innovative zero leakage control valves for liquid and gas applications. Customers are advised to consult the factory or distributor for assistance in selecting suitable products and ensuring proper installation, operation, and maintenance.

Product Overview: Cartridge Insert Lock Valves
The cartridge lock valves integrate a Kepsel® Cartridge Insert Check with a robust pilot operator, functioning similarly to the Kep-O-Lok® inline lock valve. These valves allow free flow from the valve port to the cylinder port and lock reverse flow until pilot pressure is applied. The Flexible Seal Seat ensures a bubble-tight lock to prevent load drift or circuit creep, crucial for applications like clamping cylinders or outrigger stabilizer jacks.
