Argo-Hytos Accessories

Argo-Hytos accessories cover the smaller components used to build, monitor and maintain hydraulic systems around Argo-Hytos valves, filters and reservoirs.

The Argo Hytos accessories range includes stud kits and cavity plugs for valve stacks and manifolds, cavity machining tools, the RCA push-type hand pump, valve spare parts, oil drain valves, oil level gauges and dipsticks, filter clogging indicators and MO40 and MO63 manometers.

Stud kits, cavity plugs and the RCA hand pump are zinc-coated as standard for 240 hours of corrosion protection to ISO 9227. The oil drain valves, dipsticks and clogging indicators are suitable for mineral oil and biodegradable HEES and HETG fluids.

The range splits into accessories for valves and manifolds, and accessories for filters and tanks.

Argo-Hytos Valve and Manifold Accessories

  • Stud Kits Sandwich Valve Stacks (D02, D03, D05): Stud kits for assembling ISO 4401 and DIN 24340 (CETOP 02, 03 and 05) sandwich valve stacks in size 04 (D02), size 06 (D03) and size 10 (D05). Metric threaded rod with rolled threads in high-tensile class 10.9 steel (ASTM A193 Grade B), supplied precut or uncut for cutting to length on site. When fitted to a subplate or manifold, the studs act as a guide while the stack is assembled. The hex socket nuts have the same outside diameter as a standard socket head cap screw.
  • SCP Standard Cavity Plugs: Plugs for sealing unused screw-in cartridge cavities, available in 3/4-16 UNF, 7/8-14 UNF, 1-1/16-12 UN, M20x1.5 and M27x2 threads. Each plug uses the same seals as the matching valve and has an axial bore, so it can also be used to make an optional radial port connection.
  • SMT Cavity Manufacturing Tools: Tools for machining Argo-Hytos screw-in cartridge cavities, standardised by thread size to reduce the number of tools needed across the valve range. UNF cartridges follow ISO recommendations for standard cavities. Drawings of standard tools are available on request, and special tools can be supplied.
  • RCA Push-Type Hand Pump: Screw-in cartridge hand pump for 3/4-16 UNF (RCA-A2) or M22x1.5 (RCA-RA2) cavities. Maximum generated pressure is 200 bar (2,900 psi), with displacement of 7 cm³ per stroke on the A2 version and 5 cm³ per stroke on the RA2. Built-in pressure and suction check valves, a handle beam that rotates through 360°, NBR or FPM seals, an optional dust cuff and an optional 500 mm lever. Zinc-nickel coating with 520 hours of protection is available as an alternative to the standard finish.
  • SP – Valve Spare Parts: Spare parts for Argo-Hytos directional, check, pressure control, flow control, motion control, proportional and explosion-proof valves.

Argo-Hytos Filtration and Tank Accessories

  • AV and TV Oil Drain Valves: Fitted at the bottom of a tank in place of a drain plug. A spindle opens a steel ball seal, and the threaded drain port lets oil be run into a container or drawn off by an oil pump or Argo-Hytos oil service unit with almost no spillage. AV20 (M32x1.5) and AV20/1 (M30x1.5) have an additional spindle seal; the TV (R1″) is sealed with a cap nut and flat gasket. Powder-coated malleable iron housing, fluid temperature range -30 to +100°C, maximum 1 bar absolute.
  • 3511, C5.3516 and C5.3529 Oil Level Gauges: Show oil level and oil temperature in hydraulic oil and lubricant reservoirs. Built-in thermometer, indication range up to 194 mm and temperature indication up to 80°C.
  • 0410 to C4.0464 Oil Level Dipsticks: Zinc-plated steel dipsticks with an O-ring seal, supplied with an M10 mounting bolt. Lengths of 100, 210, 310, 500 and 640 mm, with level-marked versions in some lengths. The bolt can replace one of the mounting bolts on an in-tank, return or suction filter, so no separate tapped hole is needed.
  • DG Clogging Indicators: Monitor the pressure drop across a filter element and give an optical or electrical signal, or both, when the element needs changing. DG 100, DG 101, DG 200, DG 813, DG 815, DG 819 and DG 902 suit suction and return filters, with response or switching pressures up to 2.5 bar and G¼ or M12x1.5 connections. DG 023, DG 024, DG 041 and DG 042 suit pressure and high pressure filters up to 450 bar nominal pressure. DG 060 to DG 064 have stainless steel housings for up to 600 bar nominal pressure. Both pressure filter families switch at up to 5 bar, with options including temperature suppression, two switching points, manual or automatic reset, and AMP Superseal, Deutsch DT04, M12 or DIN EN 175301-803 connectors.
  • MO40 and MO63 Manometers: Glycerine-filled pressure gauges with stainless steel cases and a pressure shock absorber in the connection fitting. MO40 has a 40 mm dial, G1/8 connection and 100 bar range. MO63 has a 63 mm dial, G1/4 connection and ranges from 40 to 400 bar. Both are available with radial or axial connections, accuracy class 1.6 and a maximum fluid temperature of 60°C.
