Imperial Valve

Imperial Valve is a specialized distributor of hydraulic components, with a particular focus on Eaton Vickers (Danfoss) vane pumps, cartridge kits, hydraulic pressure switches and hydraulic control valves for industrial and mobile hydraulic systems. With a catalog of 1,035 products, Imperial Valve offers an extensive selection of Eaton Vickers V-series and 4535V-series vane pumps for pressures up to 210 bar and flows up to 200 liters per minute.

Eaton Vickers vane pumps are the core products in the range. The 20V, 25V and 45V series are single vane pumps for industrial hydraulic systems with working pressures up to 175 bar (tandem versions up to 210 bar). The 4535V series are tandem vane pumps that integrate two pump sections in one housing for higher flow requirements. Cartridge kits (02-series) are replacement pump sets including vanes, rotor and cam ring for overhauling worn Vickers vane pumps in the field, without replacing the complete pump unit.

Eaton Vickers hydraulic pressure switches (SG307 F 150) monitor pressure in hydraulic systems at defined set values. The SG307 series are NC/NO pressure switches for pressure ranges up to 420 bar and are used in hydraulic circuits for leak indication, pump pressure monitoring and safety shutoff switches. Hydraulic counterbalance valve kits and compensators are available as replacement parts for Vickers proportional valve combinations.

Hydraulic pump groups and hydraulic cylinder mounting components complement the Imperial Valve range. Pump group accessories include hydraulic couplings, shaft seal kits, suction filters and fluid temperature indicators. Tandem pump sets with dual pump sections are available for machines with high hydraulic power requirements such as injection molding machines, hydraulic presses and bending machines.

Eaton Vickers control valves, proportional valves and servo valve kits complete the Imperial Valve range. The KBCG and KVHD series proportional directional control valves are available with internal or external drain for systems with 350 bar maximum pressure. Hydraulic PVH-series variable piston pumps with pressure and flow control are available for higher power systems requiring variable flow regulation.

At Verkopershulp.nl you will find the complete Imperial Valve range of Eaton Vickers hydraulic components with direct availability. Our technical experts support you in selecting the correct vane pump, cartridge kit or proportional valve for your hydraulic installation, including cross-reference identification for replacement of existing Vickers components.

History

Imperial Valve specializes in the distribution and supply of Eaton Vickers hydraulic components to the industrial market. Eaton Vickers has its roots in the Vickers Corporation, founded in 1922 in Detroit, USA, as a pioneer in developing hydraulic vane pumps for industrial applications. Harry Vickers received a patent in 1925 on the first commercially successful hydraulic vane pump, which laid the foundation for modern industrial hydraulics. Vickers became the most recognized name in industrial hydraulics and was acquired by Eaton Corporation in 1999, after which the products received the Eaton Vickers designation. The Danfoss Group acquired the complete Eaton hydraulics division in 2021, but the Vickers V-series vane pumps continue to be produced under the proven product lines. With more than 70 years of production history, Vickers vane pumps are the de-facto standard for industrial hydraulics worldwide.

Frequently Asked Questions

What is a cartridge kit for an Eaton Vickers vane pump?
An Eaton Vickers cartridge kit (02-series) is a complete replacement pump set consisting of vanes, rotor, cam ring and end plates of the vane pump. With a cartridge kit you can overhaul a worn or damaged Vickers vane pump in the field without replacing the complete pump housing. The cartridge kit is supplied as a precisely matched set fitting the specific pump housing.
How do I select the correct Eaton Vickers vane pump for my hydraulic system?
For selecting an Eaton Vickers vane pump you need the required flow (l/min or GPM), maximum system pressure (bar), drive motor speed (rpm) and hydraulic fluid viscosity. The 25V series is suitable for flows of 10-25 l/min at 175 bar working pressure; the 45V series for higher flows up to 100 l/min. Our technical experts help with the final pump selection.
Are Eaton Vickers vane pumps suitable for water-containing hydraulic fluids?
Yes, special Eaton Vickers vane pumps are available for use with HFA (aqueous solutions), HFB (water-in-oil emulsions) and HFC (polyglycol-water solutions) fire-resistant hydraulic fluids. Pump models for aqueous fluids have special material coatings and larger tolerances for the lower lubricity of aqueous fluids. Consult the Eaton Vickers product specification for fluid compatibility.
What is the difference between a 20V, 25V and 45V Vickers vane pump series?
The Eaton Vickers vane pump series are sized by flow: the 20V series delivers 6-12 GPM at 1,200-1,800 rpm, the 25V series 10-21 GPM and the 45V series 30-80 GPM. All series have a maximum working pressure of 175 bar continuous (210 bar peak). The 4535V tandem version combines two pump sizes in one housing for systems requiring two independent flows.
How do I identify the correct cartridge kit type for my Vickers vane pump?
The cartridge kit type number is derived from the pump type number and specifications on the pump nameplate. A pump number like 25V17A-1A22R refers to: 25V = series, 17A = 17 GPM flow, 1A22R = version code. The cartridge kit number (02-XXXXXX) is correlated to the pump type number and is listed in the Eaton Vickers parts catalog. Our experts help you with cross-reference identification.
What hydraulic oil viscosity is required for Eaton Vickers vane pumps?
Eaton Vickers vane pumps require mineral hydraulic oil with a viscosity of ISO VG 32 to ISO VG 68 at operating temperature (40°C). ISO VG 46 is the most commonly used viscosity grade for industrial hydraulic systems at ambient temperatures of 15-25°C. At low ambient temperatures (< 5°C), ISO VG 32 or synthetic hydraulic oil is recommended for rapid start-up capability.
