The Sun Hydraulics CNDEXDV (CNDEXDV) is a meticulously engineered pilot-to-close check cartridge valve, designed for robust hydraulic system applications. This valve features a spring-biased closed mechanism and includes a customer-specified bypass orifice, ensuring tailored performance for specific system requirements. The CNDEXDV operates by allowing fluid flow from port 1 to port 2 while restricting flow in the reverse direction, with the aid of a non-vented steel seat that enhances its durability and contamination resistance. The valve's operational dynamics are governed by a nominal pilot ratio of 1.8:1, meaning it requires a higher pressure at port 1 compared to the pilot port (port 3) to remain closed. This characteristic is critical in applications where control over fluid flow direction under varying pressures is necessary. The pressure at port 2 directly counters the pilot pressure, contributing to the valve's stability and reliability in maintaining its closed position under equalized pressure conditions across all ports. Constructed with Sun Hydraulics' floating style design, the CNDEXDV minimizes risks associated with internal part misalignment due to installation torque or machining variations of the cavity/cartridge. This feature ensures consistent performance and longevity of the valve even under demanding installation conditions. Technical specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 20 gpm (80 L/min), and an allowable orifice range from .016 to .107 inches (0.4 to 2.7 mm). The valve also requires an installation torque between 30 - 35 lbf ft (41 - 47 Nm) and is compatible with Viton seal kits for enhanced chemical resistance and thermal stability.

This valve is a spring biased closed, pilot-to-close check cartridge with a bypass orifice. It incorporates a steel seat and is non-vented. The valve allows flow from port 1 to port 2 and restricts flow from port 2 to port 1. Pressure at the pilot (port 3) opposes pressure at port 1 at a ratio of 1.8:1. Pressure at port 2 directly opposes the pilot pressure. Note: The bypass orifice diameter is specified by the customer. See Technical Data below for the allowable orifice range.
- Features hardened steel seats for excellent wear characteristics and contamination tolerance.
- 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.
- With equal pressures at all ports the valve is closed.
- 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.
