Hydraulic fluid must have the correct balance of cleanliness, materials, and additives for protection against wear of components, elevated viscosity, and inclusion of air. Essential information on the correct methods for treating hydraulic fluid is included in Vickers publication 56 Vickers Guide to Systemic Contamination Control available from your local Vickers distributor or by contacting Vickers, Incorporated. Recommendations on filtration and the selection of products to control fluid condition are included in 56. Recommended cleanliness levels, using petroleum oil under common conditions, are based on the highest fluid pressure levels in the system and are coded in the chart below. Fluids other than petroleum, severe service cycles, or temperature extremes are cause for adjustment of these cleanliness codes. See Vickers publication 56 for exact details.

3 Introduction For seventy five years, Vickers has provided its customers with quality products and innovative solutions for all their power and motion control needs. We are committed to maintaining this position by offering the most comprehensive range of cartridge valves for industrial and mobile equipment. This catalog gives basic specifications for the complete line of Vickers screw-in proportional control valves. Its purpose is to provide a quick, convenient reference tool when choosing Vickers proportional valves or when designing a system using these components. The products featured in this catalog represent the very best in screw-in proportional control valve technology. Products in this catalog have been fatigue tested for one million cycles at % or million cycles at 5% of rated pressure. Two pressure ratings are shown for products featured in this catalog typical application pressure and fatigue pressure. The typical application pressure is the maximum recommended operating pressure for the valve in a given system. The fatigue pressure rating is the maximum pressure for the valve to be free for infinite life from metal fatigue. The EPV has several outstanding performance features which give it a unique position in the screw-in cartridge valve market. Valve gain linearity, flow force pressure compensation characteristics above bar ( psi) and low internal leakage. The EPV6 is a proportionally controlled two-way valve of the poppet type. The main poppet amplifies a small flow through the pilot circuit and is comparable to a transistor. s the transistor uses small currents to control larger currents, the hydraulic valve transistor or VLVISTOR uses the pilotflow to control the main stage flow with servo like response. flow to control ERV- is an electric, proportionally controlled, internally pilot operated, spool type screw-in relief valve. It is capable of handling flows from,8-6, l/min (-5 USgpm) at pressures from 5- bar (5- psi). lso available is an ERV-6 which is capable of handling flows from 7,6- l/min. (-5 USgpm) at pressures from 5- bar (-5 psi). ERV- is a low flow electric proportionally controlled relief valve similar to the ERV-. This valve is rated for flows from,-,8 l/min ( USgpm) and pressures up to 5 bar (5 psi). EPRV- is an electric, proportionally controlled, internally pilot operated, spool type, screw-in pressure reducing/relieving valve. It is capable of handling flows from -7,6 l/min (- USgpm) at set pressures from 4-5 bar (-5 psi). lso available is an ERV-6 which is capable of handling flows from -8 l/min (- USgpm) at set pressures from 4-5 bar (-5 psi). Vickers proportional pressure and flow control valves are designed to be easily controlled by the simplest of DC electrical devices such as a volt battery and a potentiometer. In most cases the valves may also be simply controlled, directly, by even the most sophisticated control circuit, such as the analog out of a computer control system. In many cases, because of the coil s low current draw, the valve can be operated accurately and directly without intermediate power supplies. Current draw at the coil can be less than one amp when a volt rated coil is used, or less than.5 amp when a 4 volt rated coil is used. Varying the voltage at the coil is one of the simplest means of control available. ny of the Vickers DC coils will work on most of these valves simply by varying the voltage between and 75% of the rated coil voltage. It should be noted that as the operating temperature of a coil increases, the solenoid force decreases. Therefore if the voltage is held constant as the coil heats up then valve pressure (or flow) will decrease. Electrical current controls significantly, but not totally, overcome this problem. Closed loop electrical control with feedback from the parameter to be monitored will provide the most accurate control. Valve Features and enefits ll operating parts are hardened steel, ground and honed for long life and low leakage Designed for maximum flexibility and minimal space requirements ll exposed cartridge surfaces are zinc dichromate plated to resist corrosion Reliable, economical and compact Rated flows up to 6 l/min (4 USgpm) Optional nose in, side out or side in, nose out flow direction (EPV6 series) Coil Features and enefits The valves in this catalog are offered with a choice of two and three standard voltages and several types of electrical connections. For other coil ratings and connections, consult your Vickers representative. Variety of voltages and terminations Coils are interchangeable for serviceability on the EPV and EPV6. Coils are interchangeable for serviceability on the ERV-, EPV-6, EPRV- and EPRV-6. Compact, one-piece weather-proof encapsulated design. Eliminates need for extra seals. n arc suppression diode molded into the coil is available as a standard option on ERV and EPRV valves. WRNING: pplication of these products beyond published performance specifications may cause valve malfunction which may result in personal injury and/or damage to the machine. WRNING: For pressures over bar ( psi) use steel housing.

Sectional View Operation In the de-energized position, flow is blocked from port to port, with no reverse flow permitted.

24 EPRV-6 Proportional pressure reducing-relieving valve Functional Symbol (RP) Description The EPRV-6 is an electric, proportionally controlled, internally pilot operated, spool type, screw-in pressure reducing/relieving valve. (P) (T) Sectional View Operation This valve remains open from port to port (port must be vented). Once the predetermined pressure is reached at port, the spool shifts to restrict the inlet flow at port, which regulates the pressure at port. If the pressure at port exceeds the setting of the valve, the spool will shift farther and relieve to port.

26 C-**- Cavity Dimensions Dimensions mm (inch) 5 Cavity bores can be machined accurately in aluminum or steel. The necessary UNF, or UN threads may be machined using standard small tools, possibly already in your machine shop or from a local tool supplier. For in depth advice on the machining of cavities, consult your Vickers sales specialist. Either you, our customer, or Vickers can design and manufacture customized manifolds or housings dedicated to individual applications. We call the resulting valve packages Modular Circuit Designs (MCDs). Cartridges selected for your application can be accomodated in one or more MCDs, according to your requirements. WRNING: For EPV-, the cavity should be machined to the 4,9 (.56) maximum diameter and 6, (.47) maximum depth.

34 Supporting Products Roughing Tools Roughers are basically step drills which leave. per cutting diameter and.5 above all radii for the finishing reamer, with an additional.5 depth in the cavity bottom as clearance. The roughing tool is necessary to prepare the cavity for the finishing reamer, which has not been designed for the primary forming or bottom cutting. We offer two types of roughers, one for aluminum and one for steel. The aluminum rougher is manufactured with a 4 facet point and polished flutes. The steel rougher is supplied with a standard drill point. oth types will work in either material, however, longevity of an aluminum tool will be sacrificed when used continually in steel.
