Modular Stacking Valve System |
L Series Modular Stacking Valve SystemThe "L" Series is a manifold system made up of modular valve blocks which are stacked together and fixed with tie rods.FEATURES
The HYDAC "L" Series Modular Stacking Valve System offers a multitude of control modules that are stacked in series and fixed with two tie rods to form an integrated manifold. The manifolds may then be mounted as stand-alone packages, or as "on-board" controls for HYDAC "CA" or "HP" power units. There are three general types of modules which are used in building a manifold: Base Modules, Control Modules, and End Modules. The base module can be piped with SAE O-ring ports for remote mounting or flange-mounted to a HYDAC power unit. Control modules include a wide selection of both pressure and solenoid control valves. The end modules cap the assembly and can include other hydraulic accessory components such as pressure switches and accumulators. Features, such as 100% continuous-duty coils and leak-free solenoid and check valves, make the "L" Series ideal for extended clamping and load holding applications. |

| Module Type RL is an inline base module with no pressure controls. The unit has SAE threaded O-ring ports for the pressure and tank ports. It is used only when the maximum system pressure is controlled elsewhere in the circuit. Port P is SAE-6. Port T is SAE-8. Maximum pressure is 7250 psi. Weight is 1.3 lb. |
| Module Type L is a base module that mounts to HYSAC "CA" and "HP" Series power units. The module includes a main pressure relief valve and check valve. In addition, threaded auxiliary P and T ports are supplied. The check valve may be omitted. Three levels of relief valve pressure ranges may be selected: up to 2900 psi, up to 5000 psi, and up to 9000 psi. If no range is specified, the valve will not be set. Ports T and P are SAE-6. Maximum pressure is 7250 psi. Weight is 2.1 lb. |
| Control Module - Unloading Module is a module that houses a 2 position / 2-way solenoid valve that may be bi-directional with checks, normally open (NO) or normally closed (NC) for pressure unloading to tank. No actuator ports are supplied. Maximum pressure is 5000 PSI. Weight is 1.6 lbs. |
| Control Module P - On / Off Module is a module that houses a 2 position / 2-way solenoid valve in the pressures line to act as an ON/OFF valve for down stream modules. A normally open or normally closed valve may be selected. No actuator ports are supplied. Maximum pressure is 5000 PSI. Weight is 1.6 lbs. |
| Control Module ER - Lifting / Lowering Module with Pressure Switch uses two solenoid valves to control a single acting actuator or one side of a double-acting actuator. Jogging, or multiple positioning is possible while keeping the actuator isolated from other modules in the circuit. It may be ordered with or without a pressure switch. Port A is SAE-6. Maximum pressure is 5000 PSI. Weight is 3.2 lbs. |
| Control Module ER - Lifting / Lowering Module with Relief Valve uses two solenoid valves to control a single acting actuator or one side of a double-acting actuator. Jogging, or multiple positioning is possible while keeping the actuator isolated from other modules in the circuit. There is no provision for a pressure switch, however a relief valve is added to limit pressure spikes in overrunning load applications. Port A is SAE-6. Maximum pressure is 5000 PSI. Weight is 3.2 lbs. |
| Control Module - Clamping Module includes a 3-way / 2-position valve along with a check valve in the pressure line. It is ideal for single acting clamping applications. Port A is SAE-6. Maximum pressure is 7250 psi. Weight is 1.6 lbs. |
| Control Module K - 3-Position, 4-Way Module with All Ports Blocked consists of two 3-way/2-position solenoid valves along with cross piloted check valves combine to function as a double solenoid 4-way/3-position valve with all ports blocked in the center position. Ports A and B are SAE-6. Maximum pressure is 5000 psi. Weight is 4.8 lbs. |
| Control Module L - 3-Position, 4-Way Module with A to Tank consists of two 3-way/2-position solenoid valves and one pilot-to-open check valve combine to function as a double solenoid 4-way/3-position valve with the A line open to the tank in the center position. Ports A and B are SAE-6. Maximum pressure is 5000 psi. Weight is 4.8 lbs. |
| Control Module R - Check Valve Module consists of two check valves installed in the pressure and tank lines respectively to guard against reverse flow in system downstream of the module. Maximum pressure is 5000 psi. Weight is 1.7 lbs. |
| Control Module RM - Pressure Reducing / Regulating Module has a pressure reducing valve which will limit downstream pressure. If the module is order without the check valve, the reducing valve will also act as a relief valve - relieving back pressure from overrunning loads. Maximum pressure is 5000 psi. Weight is 1.5 lbs. |
| Control Module G - Pressure Switch Module houses two pressure switches for dual or high-low electrical signals. Maximum pressure is 7250 psi. Weight is 1.8 lbs. |
| End Module PA - Basic End Module caps manifold and has no integral functions. Maximum pressure is 7250 psi. Weight is 0.5 lbs. |
| End Module PB - End Module with Pressure Switches Two pressure switches are available to monitor and send electrical signals at the set pressures. Maximum pressure is 7250 psi. Weight is 1.3 lbs. |
| End Module PC - End Module with Accumulator Port can be used to provide rapid flow delivery, actuator leakage make-up, or as a back up source of pressure and flow for safety reasons in a power loss. Maximum pressure is 7250 psi (limited by accumulator's pressure rating). Weight is 1.5 lbs. |
| End Module PS - End module with Accumulator Port & Safety Circuit can be used to provide rapid flow delivery, actuator leakage make-up, or as a back up source of pressure and flow for safety reasons in a power loss. It also includes safety pressure relief valve along with manual valves to isolate or vent the accumulator. Maximum pressure is 7250 psi (limited by accumulator's pressure rating). Weight is 1.5 lbs. |
| Electrical Option Selection of voltage and type of connection. Required for any module with solenoid(s). All modules must be wired the same way. |
