The Sun Hydraulics DAAMDHN (DAAMDHN) is a pilot-stage, directional, 2-position, 2-way valve that offers manual operation through a variety of control options including momentary-twist, detent-lock, and dual-operation mechanisms. Designed for pilot flow applications, this manually operated cartridge valve utilizes the T8A cavity and is compatible with Sun\u2019s pilot-operated mainstage valves. The DAAMDHN model is available in both normally open or normally closed configurations, ensuring versatility for different system requirements. This valve features Sun's TwistLock manual override mechanism intended for intermittent and infrequent use only. The manual control assembly of the DAAMDHN is robust with a mechanical life expectancy of approximately 10,000 cycles and can be easily replaced in the field without disassembling the entire unit. The preferred flow path for this model runs from port 2 to port 1. Constructed to minimize internal parts binding due to excessive installation torque or cavity/cartridge machining variations, the DAAMDHN incorporates Sun\u2019s floating style construction. This design detail enhances reliability and operational smoothness across various hydraulic applications. It has a maximum operating pressure capacity of 5000 psi (350 bar) and a flow capacity of about .25 gpm (1 L/min). This cartridge valve also ensures minimized leakage at high pressures with a maximum rate of about 10 drops per minute at 5000 psi. The DAAMDHN measures with an operating torque requirement of about 10 lbf\u00b7in (1.2 Nm), facilitating ease of operation while maintaining secure performance standards. Its compact design weighs approximately .40 lb (0.20 kg) and requires specific installation torques between 20 - 25 lbf\u00b7ft (27 - 33 Nm), making it suitable for various industrial applications where space and reliability are critical.

These pilot-stage, directional, 2-position, 2-way valves are manually operated cartridges and are available in either a normally open or normally closed configuration. These cartridges are designed for pilot flow applications and utilize Sun's T-8A cavity so they can be used in conjunction with Sun's pilot-operated, main-stage valves. 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 about 10,000 cycles.
- The manual control assembly can be easily replaced in the field without removing the cartridge from the manifold or main stage element.
- 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.
- 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.
- 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.
- Utilizes the Sun T-8A 2-port cavity making it the ideal choice to use in conjunction with Sun's main stage pilot or vent-to-operate cartridges. Separate pilot lines are eliminated and only one cavity needs to be machined to accommodate both the control and primary function. Note: All 2-position, 2-way pilot stage control cartridges utilize the same cavity and are physically interchangeable. Functionality is the only consideration.
- The preferred flow path through the valve is port 2 to port 1.
- 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.
- Note: The main stage valve should first be installed to the correct torque value followed by the T-8A pilot control section into the main stage valve to its required torque value.
