Hydraulic Components & Technical Guides

IsoHydraulic is a B2B hydraulic components manufacturer based in Nanjing, China. We supply double-acting and telescopic hydraulic cylinders, CETOP solenoid valves, custom manifold blocks, honed tube and chrome-plated rod, PTFE and elastomer seals, hose assemblies and compact power units for construction, mining, agriculture and industrial OEM programs.

Engineers and buyers come to us at different stages of a project — from emergency replacements to new-machine BOMs. Matching pressure, fluid, temperature, duty cycle and environmental exposure to the right component reduces warranty claims and field failures. Our team reviews drawings, samples and field photos before quoting.

Whether you need a single NG6 solenoid valve for a field repair or a recurring supply agreement for honed tube and chrome rod, we support OEM programs and MRO buyers with cut-to-length material, EN 10204 3.1 mill certificates and export documentation. Typical lead time is 15–25 working days for custom cylinders and 7–12 days for stocked valve and seal lines, depending on bore size and quantity.

Manufacturing & Quality

Our Nanjing facility machines hydraulic cylinders, manifold blocks and power units on CNC lathes and machining centers. Honed tube is supplied in ST52/E355 with H8 bore tolerance and Ra 0.2–0.4 µm finish; chrome rod meets f7 tolerance for standard seal grooves. Directional valves are built to ISO 4401 / CETOP mounting patterns with wet-pin coils rated for 100% ED on most 24V DC NG6 models.

Every shipment can include dimensional reports, material certificates and pressure-test records on request. We do not claim third-party brand approvals — we supply functionally equivalent interchange parts and document spool codes, port sizes and coil pinouts so your maintenance team can verify fit before installation.

How to Request a Quote

Send the parameters your engineer would need to size the component: bore, stroke, rod diameter and mounting style for cylinders; NG size, spool function, voltage and connector type for valves; ID, wall thickness, length and material grade for honed tube. Include working pressure, fluid type, ambient temperature and duty cycle so we can confirm seal compatibility and coil heat rise.

For export orders, specify destination port and whether you need wooden crate packing, fumigation certificates or consolidated air freight. We respond within one business day with a bill of materials, lead time and Incoterms quote. Use the contact form below or email drawings directly to our engineering desk.

Frequently Asked Questions

What is the minimum order quantity for hydraulic cylinders?

MOQ is one piece for standard tie-rod and welded cylinders. Telescopic and large-bore custom designs may require a small batch depending on tooling — we confirm in the quote.

Do you supply Vickers DG4V equivalents?

Yes. We cross-reference DG4V-3 and DG4V-5 spool codes, voltage suffixes and CETOP subplates. See our DG4V cross-reference guide before ordering.

Which honed tube grades do you stock?

ST52.3 and E355 carbon steel are standard; 20MnV6, 42CrMo4 and 304/316 stainless are available on mill order. Cut lengths from 100 mm to 6000 mm with deburred or chamfered ends.

Can you ship internationally?

We export worldwide from Nanjing, China. Commercial invoices, packing lists and certificates of origin are prepared for each shipment. Sea freight, air freight and express courier are available.
