Additional indirect costs savings may be possible:
1. Lowering air flow needs and inlet pressure may prevent the need to acquire additional air compressor capacity.
2. The need for speed regulators is reduced. A special valve called a flow control valve or "speed regulator" is usually used at each end of a cylinder to break or cushion the air at the end of a stroke. The air pressure created in the X-Block® internal circuit serves as an air "cushioning" to soften the forward stroke's impact. The speed regulator on the negative cylinder side becomes redundant and can be removed. The speed regulator on the positive side should be changed to switch air direction.
3. Valve requirements are simpler since the return stroke is set in motion automatically whereas in a standard system the return is started from the valve. Valves can be changed to a simpler version (i.e. from 5/2 to 3/ 2 valve).
|
In the X-Block® configuration only three port valves (3/2) are required instead of five port valves (5/2) normally needed to run double acting cylinders. (However, the valves do not need to be changed in an existing set-up).
