2 V, DV, ND RORY DIREIONL ONROL VLVES; FOR FLOWS U O 20 GM (76 LM) ND WORKING RESSURES U O 2,500 SIG (172 R) SRING REURN ND DEEN OIONS; RESSURES O 2,500 SIG (172 R) hese 20 GM (76 LM) manual spool valves are available with an externally adjustable pressure relief valve on all but the closed center models. NOE: he maximum recommended flow rate for the internal relief valve at 2,500 SIG (172 bar) is 10 GM (38 LM). hey are offered in both three-way and four-way versions, with a wide range of spool options available. V designated models feature spring-centered operation, while DV designated models feature mechanical spool detents. he valve bodies are constructed from fine gray iron castings, and the spools are precision ground and chrome-plated steel. ressure and return ports are 3/4 inch NF, and cylinder ports are either 1/2 inch or 3/4 inch NF. SE o-ring boss ports are also available as an option. Relief valve pressure ranges are 400 to 2,500 SIG (28 to 172 bar). If not customer specified, assemblies are automatically furnished with relief set at 2,000 SIG (138 bar) at 10 GM (38 LM). For units without a relief valve function, please consult our factory. Weights: V Series 9 lbs. (4.1 kg) DV Series 9-1/2 lbs. (4.3 kg) UION: Relief valve pressure adjustments should not be made while the system is under pressure. WRNING: V & DV valves do not contain load checks and therefore should not be used in lifting applications unless some other means of holding the load is provided by the customer.

NOE: he maximum recommended flow rate for the internal relief valve at 2,500 SIG (172 bar) is 10 GM (38 LM). UION: Relief valve pressure adjustments should not be made while the system is under pressure. WRNING: hese valves do not contain load checks and therefore should not be used in lifting applications unless some other means of holding the load is provided by the customer.

Flow is controlled by a simple pull or push of the control knob or handle. he spools are held in position by the frictional force of their o-rings, effectively creating a detent in either position (except for spring-return models).

HR Series ylinders ie-rod design; 3,265 psig (225 bar) working pressure capability. Rephasing ylinders rephrasing cylinder system is two or more cylinders plumbed in series, with the bore and rod diameters sized such that all rods extend and/or retract an equal or equivalent amount when flow is applied to the first, or last, cylinder in the series. his hydraulic synchronization of rod positions typically eliminates the need for a hydraulic flow divider and/or combiner, or a mechanical connection between the cylinder rods in the application. lease contact us for further details and information regarding these systems.
