The Sun Hydraulics DNDMTYN (DNDMTYN) is a manually operated, 2-position, 4-way directional cartridge valve designed for controlling the direction of flow in hydraulic circuits. This direct-acting, balanced spool valve features Sun's TwistLock manual override mechanism, intended for intermittent and infrequent use. The control mechanism offers three options: momentary-twist (T), detent-lock (L), and dual-operation (D). The momentary-twist option allows the operator to temporarily shift the valve by twisting the knob clockwise; it returns to its normal position upon release. The detent-lock option enables shifting into a mechanically detented position by twisting counterclockwise, but it is not suitable for load holding applications. The dual-operation option provides both momentary and detented shifting capabilities. This valve must be operated manually without modification or mechanical devices. The DNDMTYN incorporates Sun's floating style construction to minimize binding due to excessive installation torque or machining variations. It fits into a T-31A cavity with a series 1 capacity of 10 gpm (40 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). The valve has a maximum leakage rate of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar) when using hydraulic oil with viscosity of 110 SUS (24 cSt). It requires an operating torque of 10 lbf-in (1.2 Nm) and should be installed with a torque between 30-35 lbf-ft (41-47 Nm). Cartridges equipped with EPDM seals are compatible with phosphate ester fluids but are susceptible to damage from petroleum-based substances.

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.
