Soft Engage Valve
The soft engage valve is a pilot operated valve mounted between the control valve and hydraulic starter within the starting system. As the system fluid passes through the control valve, a small amount of oil is delivered to the starter allowing the smooth engagement of the pinion gear and the flywheel ring gear. Once the gears mesh, the valve opens completely and delivers full system fluid. The result is a smooth, powerful engine start.
Control Valves
Kocsis Hydraulics offers several options when it comes to control valves. For those who are looking to actuate the hydraulic starting system manually, the two main options include foot pedal actuated and Bowden wire actuated valves. For operators interested in controlling starting system actuation via HMI (panel interface), Kocsis Hydraulics offers several options of solenoid operated valves that meet industry requirements including explosion proofing.
Hand Pump
The Kocsis Hydraulics hand pump is a manual pump capable of regenerating system pressure for a starting attempt. Equipped with a 3-foot lever, the manual pump operates on “human” power and can recharge a hydraulic system in a black start condition. The Kocsis Hydraulics hydraulic starting system is the only system capable of being recharged manually thus one more reason why it’s relied upon in emergency starting applications.
Recharging Pump
Offered in numerous variations, the Kocsis Hydraulics recharging pump is driven by some form of a prime mover (engine PTO or electric motor) to recharge the hydraulic starting system for starting attempts. Featuring a built-in unloading valve, the recharging pump unloads when system pressure has been reached. While in this state, the pump is fully lubricated and can run continuously without issue.
Fluid cleanliness not only improves the life of a system but also increases reliability. Kocsis Hydraulics filters help fight contamination without adding a significant fluid restriction. Both the inline high-pressure filter and low-pressure suction t-filer are equipped with 40-micron ratings and provide the system with the necessary filtration for dependable starting.
Tanks & Reservoirs
Kocsis Hydraulics offers a full line of reservoirs in various capacities: 4, 7.5, 12.5, and 15 gallons. Our tanks feature painted heavy gauge steel with a fully removable lid for easy maintenance. The filler breather cap is made of high-quality chrome-plated steel. Each tank includes an easily readable sight level gauge which conveniently allows the monitoring of oil in the system.
