Browse a range of Yale and Pfaff accessories for hydraulic lifting cylinders. Manifolds are used when different pressures must be maintained in each hydraulic line. Therefore, they allow the lifting of unequal loads. Manifolds are ready assembled and can be screwed directly to a hand pump or power pack. The model VSM-11 can be directly screwed into the oil port of a hydraulic cylinder and works at this location as a “hose break fuse“. The design of the VSM-21 is suitable for a combination with VHP directional valves. Pfaff hydraulic maintenance repair sets are indispensable in factories and workshops. They provide controlled hydraulic force for universal applications, such as pressing, straightening, lifting, flattening, pushing bolts, bending, spreading, tensioning, etc. Clevis eye mountings are screwed onto the piston and bottom of the hydraulic cylinder, in those cases where conditions require pivoting of the cylinder. Extension tubes are mounted onto the bottom of cylinders series YS by means of the base adaptor and two hexagon socket screws (screws are included with the base adaptor). The use of extension tubes adds to the versatility of the standard cylinders. In connection with the corresponding hydraulic cylinder, a lifting claw represents a compact, lightweight and versatile lifting unit. Piston plates reduce the surface pressure and prevent the pistons from sinking into the ground and support base plate prevent the cylinders from falling over and sinking into the ground. The use of Yale GGY pressure gauges is recommended when the operating pressure (the force of the connected cylinder) should be monitored. Yale pressure gauges are equipped with a stainless steel housing and an acrylic plastic face cover plate. Manifolds are used when several hydraulic cylinders have to be connected to one hydraulic pump.
