Standard Check Valves
Brand: Parker HannifinCapable of flows from 3.5 to 303 lpm (0.9 to 80 gpm) and pressure as high as 420 bar (6,000 psi), Parker’s poppet and ball style check valves have a simple and robust design which are used to block flow in one direction, and allow flow in the opposite.
Parker’s robust poppet and ball style check valves are designed for the most demanding applications with flows up to 303 lpm (80 gpm) and pressures as high as 420 bar (6,000 psi) across several markets such as agriculture, construction, and industrial manufacturing.
These valves feature a hardened poppet or ball and seat design that keeps leakage as low as 5 drops per minute or less while lengthening service life due to improved wear characteristics, and the wide selection of crack pressures available ensures easy system integration with reliable performance.
Features- Wide range of body sizes, crack pressures, and flow capacities
- Low leakage – less than 5 drops/min
- Simple construction – extremely cost effective
- High tolerance for contamination
- All external parts zinc plated
