This new valve is ideal for both pneumatic and hydraulic pressure relief applications where zero leakage is needed. The cracking pressure is preset at the factory with capabilities ranging from 20 psid up to 100 psid. The nominal weight is only 1.5 grams. Each Zero Leak PRI is 100% tested and inspected to ensure reliable, consistent performance.
  3. 200 Series Radial Piston Pump

    200 Series Radial Piston Pump
    The Lee Company introduces the latest achievement in miniaturization - the Lee 200 Series Positive Displacement Pump. Its unique radial piston design aids in self-priming at altitude and reduces cavitation.
  4. 250 Inverse Lee Shuttle™ Valve

    250 Inverse Lee Shuttle™ Valve
    The Lee Company's new 250 Inverse Shuttle Valve is the latest addition to Lee's line of miniature inverse shuttle valves. The poppets in this shuttle valve are designed to allow the lower inlet pressure to flow while the higher inlet pressure is blocked.
  5. 250 Series Solenoid Valve

    250 Series Solenoid Valve
    The Lee Company's new 250 Series Solenoid Valve sets a new standard in reducing space, weight and power consumption. Designed for 28 volt systems, this 2 position, 3-way miniature piloting solenoid valve features Lee's field proven Piloting Solenoid coil, as well as Lee's unique and patented MultiSeal™ technology. The one-piece MultiSeal provides reliable sealing both axially and radially, minimizing the size of the hydraulic interface. It's omni-directional design allows porting flexibility without the need for O-Rings or anti-Extrusion Rings.
