The Sun Hydraulics DNDMTHV (DNDMTHV) is a manually operated, 2-position, 4-way directional cartridge valve designed to control the flow direction in hydraulic circuits. It features a direct-acting, balanced spool valve mechanism and utilizes Sun's TwistLock manual override for operation. This valve is intended for intermittent use, such as manual overrides, and has a mechanical life expectancy of approximately 7,000 cycles. The momentary-twist control option allows temporary shifting by twisting the knob clockwise and releasing it to return to its normal position. Alternatively, the detent-lock option enables the operator to twist the knob counterclockwise into a mechanically detented position for temporary shifting; this position is not suitable for load holding applications. Additionally, the dual-operation control provides both momentary and detent-lock functionalities. The valve is designed to be hand-operated and should not be modified or operated by mechanical devices. It incorporates EPDM seals suitable for systems with phosphate ester fluids and uses Sun's floating style construction to reduce binding risks during installation. Key specifications include a T31A cavity size, Series 1 classification, a capacity of 10 gpm (40 L/min), maximum operating pressure of 5000 psi (350 bar), maximum leakage at specified conditions of 10 in\u00b3/min (160 cc/min), an operating torque of 10 lbf-in (1.2 Nm), a valve hex size of 7/8 in (22.2 mm), and an installation torque range of 30-35 lbf-ft (41-47 Nm). The Viton seal kit part number is 990431006.

This manually operated, 2-position, 4-way directional cartridge is a direct-acting, balanced spool valve used to control the direction of flow in a hydraulic circuit. Manual operation is achieved via Sun's Twist/Lock manual override mechanism and is designed for intermittent (infrequent) use only.
- This valve is designed for intermittent use such as a manual override. The manual control assembly has a mechanical life expectancy of approximately 7,000 cycles.
- The momentary/twist control option "T" allows the operator to momentarily shift the valve by twisting the knob clockwise and releasing. Once released, the valve returns to its normal position.
- The detent/lock control option "L" allows the operator to shift the valve into a mechanically detented position by twisting the knob counter-clockwise. This detented position will be maintained until the operator twists the knob clockwise and allows the valve to return to its normal position. Please note that the detented position is not intended for load holding applications but for temporary shifting only.
- The dual-operation control option "D" allows the operator to either shift the valve momentarily by twisting the knob clockwise or shift it into a mechanically detented postion by twisting counter-clockwise. Please note that the detented position is not intended for load holding applications but for temporary shifting only.
- The control on this valve is meant to be operated by a person's hand. The control should not be modified, for instance fastening a lever to the knob. Under no circumstances should the control be operated by other mechanical devices.
- Cartridges with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- 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.
