The Sun Hydraulics FTDALCV (Material Number: FTDALCV) is a 2-way, 2-position proportional throttle valve designed for precise flow control in hydraulic systems. This valve features ports 2 and 3 that are normally closed, while pilot pressure at port 1 opposes the spring to create a variable metering orifice between ports 2 and 3, with flow proportional to the pressure at port 1. The design includes a dual path with double port areas at ports 2 and 3, providing partial self-compensation as load pressure changes. For enhanced pressure compensation, external modulating logic elements like LRCXHN for bypass circuits or LPCXHN for restrictive circuits can be employed. The FTDALCV valve supports accurate flow control by maintaining a constant pressure differential across the valve. Additional features include an optional stroke adjustment (L control) to limit maximum flow and Sun's floating style construction that minimizes internal part binding due to excessive installation torque or machining variations. The valve operates within a cavity T-52A and is part of Series 2, offering a capacity of up to 30 gpm (120 L/min). It requires a minimum pilot pressure of 80 psi (5.5 bar) to shift and full shift at rated flow needs pilot pressure of up to 300 psi (20 bar). The maximum operating pressure is rated at 5000 psi (350 bar), with maximum leakage limited to 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). Installation requires a torque between 45-50 lbf ft (61-68 Nm), and it is compatible with Viton seal kits for reliable performance under various conditions.

This valve is a 2-way, 2 position, proportional throttle. Ports 2 and 3 are normally closed. Pilot pressure at port 1 opposes the spring and creates a variable metering orifice between port 2 and 3 that is proportional to the pressure at 1. The force balance of the flow forces, spring and pilot pressure results in a degree of partial self-compensation as the load pressure changes.
Pressure at port 4 directly opposes pressure at port 1.
The valve uses a dual path design. Ports 2 and 3 incorporate a double port area.
- These valves may be pressure compensated by an external, modulating, logic element. Use LR_C-XHN for a bypass circuit or LP_C-XHN for a restrictive circuit.
- The valve provides a degree of self-compensation and may be used as a flow control. To increase the accuracy of flow control, an external, modulating, logic element can be used to maintain a constant flow over a wider range of flows and pressures. See performance curves for additional information.
- The optional L control is a stroke adjustment that limits maximum flow.
- Ports 1 and 4 should be limited to 500 psi (35 bar).
- Pressure at port 4 directly opposes pressure at port 1.
- Accurate pressure compensated control requires that a constant pressure differential be maintained across the valve.
- 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.
