Check Valve (CV-1) AC Lift
Frequently Asked Questions
Q: What is the purpose of the RA 1014626/001 check valve?
A: The RA 1014626/001 is an AC lift check valve (CV-1) designed for AC-powered or three-phase powered material handling equipment. It maintains pressure control and prevents reverse flow in AC-powered lift circuits.
Q: How does the AC version differ from the DC check valve RA 1013281/005?
A: The RA 1014626/001 is configured for AC lift systems, while RA 1013281/005 is for DC lift systems. The internal specifications, pressure ratings, and flow characteristics are optimized for their respective power supply architectures. Do not interchange between AC and DC systems.
Q: Which Raymond equipment models are compatible with RA 1014626/001?
A: The RA 1014626/001 is compatible with Raymond reach trucks, pallet jacks, and other material handling equipment equipped with AC lift circuits. Verify your equipment uses AC or three-phase lift power before ordering.
Q: What causes check valve failure in AC lift systems?
A: Common failures include seal degradation from contaminated hydraulic fluid, poppet stiction due to varnish buildup, or internal erosion from high-frequency pressure cycling. Maintaining hydraulic fluid cleanliness extends valve life significantly.
Q: What pressure ratings should I verify for the RA 1014626/001?
A: Check the equipment manual and nameplate for system operating pressure and relief valve setting. The RA 1014626/001 is rated for standard industrial AC lift circuits, typically 2000 to 3000 PSI. Do not use this valve in systems exceeding design pressure.
