The Yale MY range comprises hydraulic manifolds rated for 700 bar, used when several hydraulic cylinders connect to one hydraulic pump. Three standard models cover 6, 4 and 7 outlet ports. All manifolds use 3/8 NPT inner oil ports, accepting fittings, hydraulic hoses and couplers from across the Yale 700 bar range.
Distribute one pump's flow to multiple cylinders
Yale states that to connect a manifold directly to a hand pump, an FY-1 double nipple is recommended. Each manifold is supplied with three steel blind plugs in case not all the oil ports are required. Yale also offers MY manifolds with integrated shut-off valves (MY-22, MY-44, MY-66) for applications where different pressures must be maintained in each hydraulic line. GYA versions add pressure gauge sets for permanent reading of each individual load.
Suitable Applications
Per Yale: multi-cylinder synchronised lifting from one pump, parallel rigging, hydraulic lifting beams. Yale uses MY-44 manifolds in custom power pack configurations - the MY-44-GYA version with VSM-21 safety check valve enables pressure-independent control of 4 single-acting cylinders with individual pressure monitoring.
Every part of the circuit carries a pressure rating, and the system is limited by its lowest-rated component — check these against the pump and cylinder in use.

Frequently Asked Questions
Q: Which MY fits my application?
MY-1 (6 ports), MY-2 (4 ports), MY-4 (7 ports). For independent pressure control per cylinder, choose MY-22 or MY-44 with shut-off valves. For full pressure monitoring per cylinder, choose the -GYA variants.
Q: How do I connect the MY to a hand pump?
Yale recommends the FY-1 double nipple to connect a manifold directly to a hand pump.
Q: Are unused outlets a concern?
Yale supplies each manifold with three steel blind plugs to cap unused outlets.
