The lock valve combines a Kepsel® Cartridge
Insert Check with a rugged pilot operator. They free flow from valve port to
cylinder port (or to portion of circuit) and “lock” reverse flow
until pilot pressure is applied to unlock the internal check valve and allow
reverse flow. Kepner's Flexible
Seal Seat™ provides positive
bubble-tight locking to prevent load drift or circuit creep, and answers the
need where internal leakage could adversely affect performance such as with
clamping cylinders or outrigger stabilizer jacks. Standard and specialty valve
designs handle a wide variety of applications for dependable position and load
holding, including safety holding against line rupture or control valve leakage.
