Who is Sun Hydraulics and what does it make?

Sun Hydraulics is an American manufacturer of cartridge valves and hydraulic manifolds, headquartered in Sarasota, Florida. Sun Hydraulics has its own factories in Europe — in Coventry (United Kingdom), Erkelenz (Germany) and Roncolo (Italy) — which means a production and technical support network already present on the continent. For Romania we can quote cartridge valves from the core range — load holding, relief and directional valves — for mobile and stationary hydraulic systems.

The Sun Hydraulics model code is a four-letter identifier (for example CBCA, CBGL, RBDA), often followed by a second group of letters for the construction variant (CAN, LHN, LBN, etc.). The range of counterbalance valves, which includes the codes CBCA, CBEG or MWGA, holds a suspended load safely even if the system pressure drops suddenly — a critical function on mobile machines with a hydraulic boom. Bidirectional relief valves (RBDA, RBFA) limit the peak pressure in both flow directions, useful in circuits with a reversible pump.

For the Romanian market, the Sun Hydraulics range makes sense on mobile machines, lifting equipment or hydraulic lines where safety against load drop or limiting peak pressure are project requirements, not just options.

What do we supply from the Sun Hydraulics range?

Product	Description
Counterbalance Valves (Load Holding)	Family of cartridge valves that hold a suspended load in a safe position when the pressure in the hydraulic circuit drops unexpectedly, for example when a hose bursts. The codes in the range (CBCA, CBCH, CBGL, CBEG, MWGA, MWEA, CAGL, CAIG) differ by pilot ratio, flow capacity and construction variant; for example CBCA has a 3:1 ratio and 15 gpm (60 L/min), while MWGA has 3:1 and 60 gpm (240 L/min). Mounted directly in a block or on a manifold, they are typical for hydraulic booms and forestry machines.
Bidirectional Relief Valves	The codes RBDA and RBFA limit the maximum pressure in the circuit regardless of the flow direction, and are suitable for circuits with a reversible pump or a bidirectional hydraulic motor. Direct-acting construction, with no external piloting, which simplifies manifold mounting. Useful for protecting downstream components from pressure peaks caused by load shocks.
Solenoid Directional Valves	The code DFDJ is a poppet-type directional valve, with a solenoid, 2-way and two-stage (piloted) operation, available normally closed or normally open, for on/off control of flow in a hydraulic circuit. The poppet construction reduces internal leakage when the valve is closed, an advantage in systems where energy efficiency matters. It is fitted directly in custom manifold bodies, alongside the pressure valves from the same range.

How do we supply Sun Hydraulics in Romania?

What we confirm for Sun Hydraulics: the manufacturer's factories in the United Kingdom, Germany and Italy appear in the manufacturer's documentation, but we confirm availability at each of them in the quotation. We supply Sun Hydraulics cartridge valves to order, usually within 1–4 weeks, depending on the model code and the confirmation of availability at the relevant European factory. For a quotation, send the model code — for example CBCA/LHN — or the functional parameters: pressure, flow, pilot type.

We check the stock of the manufacturer's European factories for each code at the time of the request.

Frequently asked questions about Sun Hydraulics

What product range does Sun Hydraulics have?

Sun Hydraulics makes cartridge valves and hydraulic manifolds — load holding, relief and directional valves — used in mobile machines, lifting equipment and stationary hydraulic lines, with its own factories including in Europe.

How do I choose a Sun Hydraulics valve by code?

The model code, made up of four letters followed by a second group — for example CBCA/LHN — indicates the valve function and the construction variant; compare the function required with the pressure and flow parameters of your circuit to choose correctly.

Can Sun Hydraulics be sourced in Romania/Europe?

Yes — the manufacturer has its own factories in the United Kingdom, Germany and Italy, according to the manufacturer's documentation, which means a European network already in place; we supply the valves to order, usually within 1–4 weeks.

How do I choose a Sun Hydraulics counterbalance valve?

Each code — CBCA, CBGL, MWGA, etc. — has a specific pilot ratio and flow capacity; send the existing code or the pressure and flow parameters, and we will check the suitable variant from the current range.

How do I request a Sun Hydraulics quotation?

Send the Sun Hydraulics code from the nameplate and the quantity; we reply in English with availability and the lead time written in the quotation.
