The Sun Hydraulics DTDMLHN (DTDMLHN) is a manually operated, 2-position, 2-way directional cartridge valve designed for controlling flow direction in hydraulic circuits. This direct-acting, poppet-style valve is available in either a normally open or normally closed configuration and features Sun's TwistLock manual override mechanism, intended for intermittent and infrequent use. The poppet-style construction ensures extremely low leakage rates of less than 10 drops per minute at a maximum operating pressure of 5000 psi (350 bar). The valve offers three control options: momentary-twist (T), detent-lock (L), and dual-operation (D), providing flexibility in operation by allowing temporary shifting of the valve position. Notably, the detented position is not suitable for load holding applications but only for temporary shifts. The DTDMLHN is capable of handling flow capacities up to 10 gpm (40 L/min) and incorporates Sun's floating style construction to minimize internal binding due to installation torque or machining variations. It is housed within a T-13A cavity and requires an installation torque between 30-35 lbf ft (41-47 Nm). For systems using phosphate ester fluids, cartridges with EPDM seals are recommended, as exposure to petroleum-based substances can cause damage to these seals. The valve's mechanical life expectancy stands at approximately 7,000 cycles when used as intended.

This manually operated, 2-position, 2-way directional cartridge is a direct-acting, poppet-style valve used to control the direction of flow in a hydraulic circuit. The valve is available in either a normally open or normally closed configuration. Manual operation is achieved via Sun's Twist/Lock manual override mechanism and is designed for intermittent (infrequent) use only. Due to the poppet-style construction, this valve has extremely low leakage.
- 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.
- Valves exhibit extremely low leakage rates; less than 10 drops/min. @ 5000 psi (0,7 cc/min @350 bar).
- This valve is suitable for load holding applications when using the Normally Closed option. The detent mechanism in the manual override is meant for temporary actuation.
- 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.
