The Sun Hydraulics COKAXEV (COKAXEV) is a high-performance, pilot-to-close check cartridge valve designed for efficient hydraulic control in various applications. This valve facilitates flow from port 1 to port 2 while effectively blocking any reverse flow, ensuring operational reliability and fluid control precision. With a nominal pilot ratio of 1.8:1, the COKAXEV can close against significantly higher pressures at port 1 when controlled pressure is applied at the pilot port. This feature makes it particularly suitable for use in regeneration circuits where such control dynamics are required. The valve is engineered to operate within Sun's T19A cavity at reduced capacities; however, to achieve its full capacity of 240 gpm (900 L/min), the T19AU cavity should be utilized. The maximum operating pressure for this model is rated at 5000 psi (350 bar), with a maximum valve leakage specified at less than one drop per minute (0.07 cc/min), showcasing its efficiency and robust sealing capabilities. For installation, the COKAXEV requires a hex size of 1 5/8 inches (41.3 mm) and an installation torque between 350 and 375 lbf\u00b7ft (474 \u2013 508 Nm), ensuring a secure fit and minimizing potential leakage paths. Weighing approximately 2.60 lbs (1.20 kg), this model incorporates Sun\u2019s floating style construction which aids in reducing internal parts binding\u2014a common issue due to excessive installation torque or cavity/cartridge machining variations. Designed with corrosion resistance in mind, specific models like those suffixed with AP or LH are tailored for corrosive environments, extending the valve's lifespan and reliability in harsh conditions. The COKAXEV's design and capabilities make it an essential component for sophisticated hydraulic systems requiring precise flow regulation and high-pressure endurance.

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.
- These valves will work in Sun's standard T-19A cavity at lower capacity. To realize the full stated capacity, the T-19AU cavity should be used.
- 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.
- 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.
