The Sun Hydraulics DAAPEHN (DAAPEHN) is a pilot-stage, directional, 2-position, 2-way valve designed for pneumatic operation with a spring-return mechanism. This valve is available in either normally open or normally closed configurations, catering to various application needs. It is engineered to fit the Sun T8A cavity, which facilitates integration with Sun's pilot-operated mainstage valves. The utilization of the T8A 2-port cavity simplifies installation by requiring only one cavity for both control and primary functions, thereby eliminating the need for separate pilot lines. The DAAPEHN valve supports a preferred flow path from port 2 to port 1 and offers options for different pilot control ports. The construction includes a hardened spool and sleeve that ensure consistent operation, low leakage rates, and enhanced wear resistance. The minimum pilot pressure necessary for operation ranges from 20 to 70 psi (1.4 to 5 bar), calculated based on the pressure at Port 1. This valve can handle a maximum operating pressure of up to 5000 psi (350 bar), except for the pilot port which can accept up to 500 psi (35 bar). It features Sun\u2019s floating style construction which minimizes internal parts binding due to variations in installation torque or machining inaccuracies. The DAAPEHN is also characterized by its compact design with a hex size of 7/8 inches (22.2 mm) and an installation torque requirement between 20 and 25 lbf.ft (27 - 33 Nm). It supports a flow capacity of up to .25 gpm (1 L/min) and showcases maximum valve leakage at high pressures not exceeding ten drops per minute at 5000 psi or approximately 0.7 cc/min at 350 bar.

These pilot-stage, directional, 2-position, 2-way valves are pneumatically operated, spring-return cartridges and are available in either normally open or normally closed configurations. 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.
- 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.
- 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.
- The preferred flow path through the valve is port 2 to port 1.
- Different pilot control port options are available. See Option Selection for details.
- Hardened spool and sleeve provide consistent operation, low spool leakage rates and superior wear characteristics.
- The minimum pilot pressure required to operate the valve is determined by the following formula: pilot pressure = 20 psi + pressure @ Port 1 divided by 100. This results in a pilot pressure range of 20 to 70 psi. In metric; pilot pressure = 1,4 bar + pressure @ Port 1 divided by 100. This results in a pilot pressure of 1,4 to 5 bar.
- All ports will accept 5000 psi (350 bar) with the exception of the pilot port which accepts 500 psi (35 bar) max.
- 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.
