The Sun Hydraulics DTDMTHV (Material Number: DTDMTHV) is a manually operated, 2-position, 2-way directional cartridge valve that controls the flow direction in hydraulic circuits. This direct-acting, poppet-style valve is available in normally open or normally closed configurations and features Sun's Twist-Lock manual override mechanism for intermittent and infrequent use. The valve boasts extremely low leakage due to its poppet-style construction, making it suitable for load holding applications when using the Normally Closed option. It offers three control options: momentary-twist (T), detent-lock (L), and dual-operation (D). The momentary-twist allows temporary shifting by twisting the knob clockwise, while the detent-lock maintains a mechanically detented position until manually reset. The dual-operation combines both functionalities but is not intended for load holding applications. The valve's control is designed for manual operation only and should not be modified or operated by mechanical devices. It has a mechanical life expectancy of approximately 7,000 cycles. The DTDMTHV incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations in cavity/cartridge designs. It fits into a T-13A cavity with a series 1 capacity of 10 gpm (40 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). Maximum valve leakage at 110 SUS (24 cSt) is less than 10 drops/min at 5000 psi. Installation requires a torque of 30-35 lbf ft (41-47 Nm). For systems using phosphate ester fluids, EPDM seals are recommended as exposure to petroleum-based fluids may damage them.

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.
