The Sun Hydraulics CODALAV (CODALAV) is a finely engineered pilot-to-close check cartridge valve designed for high-performance hydraulic systems. This valve facilitates controlled flow from port 1 to port 2 while preventing any reverse flow from port 2 to port 1 under all conditions, ensuring operational reliability and safety. The valve features a nominal pilot ratio of 1.8:1, which means that a pressure of 1000 psi at the pilot port can close the valve against a pressure of 1800 psi at port 1. This characteristic is particularly beneficial in regeneration circuits where precise control over fluid flow is necessary. The CODALAV model incorporates Sun Hydraulics' floating style construction which minimizes internal parts binding, a common issue in valves due to excessive installation torque or cavity/cartridge machining variations. It also boasts minimal leakage with maximum valve leakage specified at only one drop per minute at 110 SUS (24 cSt). The design includes EPDM seals suitable for systems using phosphate ester fluids, though these seals are vulnerable to damage when exposed to petroleum-based fluids. With its robust construction, the valve can handle a maximum operating pressure of up to 5000 psi (350 bar) and has a flow capacity of up to 20 gpm (80 L/min). Installation specifications recommend a torque between 30-35 lbf ft (41-47 Nm), and the valve itself has a compact weight of .30 lb (0.15 kg), making it easy to handle and install. The T11A cavity design and Series 1 classification further define its configuration specifics, ensuring compatibility with various hydraulic setups. Overall, the Sun Hydraulics CODALAV check cartridge is an essential component for hydraulic systems requiring reliable one-way flow capabilities with high-pressure endurance and precise control features.

This valve is a spring biased closed, pilot-to-close check cartridge that has a 1.8:1 pilot ratio. The valve allows flow from port 1 to port 2 and blocks reverse flow. Pressure at the pilot port opposes pressure at port 1 at a ratio of 1.8:1. This valve is most often used in regeneration circuits.
- Minimum clearances between the spool and sleeve and a seal on the pilot piston diameter significantly reduce the potential for silting.
- Nominal pilot ratio is 1.8:1. This means that a pressure of 1000 psi (70 bar) at the pilot port will close a valve against a pressure of 1800 psi (125 bar) at port 1. Any decay or loss of pilot pressure could allow the valve to open, even if it is a momentary decay or loss.
- Pressure at the port 2 area directly opposes pilot pressure.
- Reverse flow through the valve from port 2 to port 1 is not possible under any condition.
- With equal pressures at all ports the valve is closed.
- In the begining the CO*A's did not have a positive seal on the pilot pistons and the CO*B's did. Now the CO*A's are positively sealed and the 2 valves are mechanically identical. CO*A's are more readily available and cost less.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- Corrosion resistant cartridge valves are intended for use in corrosive environments and are identified by the model code suffix /AP or /LH (see CONFIGURATION section). For further details, please see the Materials of Construction page under TECHNICAL RESOURCES.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
