Hand pumps for double-acting hydraulic cylinders model HPH
With
4-way valve and relief valve (hand wheel)
All Yale hand pumps of the type HPH are designed as double-acting
cylinders. Basically they do not differentiate from the
series HPS, but are equipped with a 4/3-way directional
valve.
The fine adjustable
relief valve remains unaffected and permits a sensitive
pressure relief. Pressure gauge and adaptor can be delivered
as accessories.
