Windsor, CT - Jacobs, the manufacturer of Jake brakes for the trucking industry, is using a new, "patent allowed" DO3 pneumatic valve from Interface Devices, Inc. (Milford, CT) which provides leak-free operation in work-holding applications up to 6,000 psi at the plant. Jay Schrager, manager of the machine design and build department at Jacobs, is testing several of the new DO3's at the company's manufacturing plant where the engine brakes are made. "Preliminary results are impressive," says Schrager.
The new DO3 from Interface Device eliminates the disadvantages encountered with traditional four-way options. It eliminates leakage by using simplified poppet circuitry. It also requires only 15 VA inrush and 5 VA holding, a fraction of what a shear-slide valve requires. The valve's designer eliminated the need for high-energy demands by utilizing internally pilot-operated valving.
The inclusion of an optional P port check valve makes the IDI valve fail-safe if the P port loses pressure. If a pressure switch located in the clamped cylinder line is set to turn off power to both the pump and the valve after reaching a desired pressure, the check valve maintains pressure. If pressure decays more than a desired set percentage, the pressure switch momentarily re-energizes the valve and turns on the pump until the clamp or other work holding device regains desired pressure.
Jacobs operates approximately 100 Interface Device air-over-oil pumps each using multiple DO3s for a variety work-holding applications. Schrager anticipates replacing the existing four-way spool valves with the new DO3 valves throughout the plant this year.
