A new S-Transfer Parallel Valve System from Leslie Controls has been added to the Leslie Control’s line of valve systems. This new system is simple and versatile while maintaining the ability to handle wide load variations beyond what a single valve can carry.

The system is made of a combination of control valves and regulators that “transfer” flow from the valve that works the best for the current steam load. When this kind of system is freshly installed, it can result in safety valve “popping” problems that also result in intermittent steam main pressure problems.

In the main “brains” of the S-Transfer System is a pneumatic switch that selects which parallel circuits will be active to prevent oscillation between the circuits. Only one valve is open at any given time, and neither valve throttles close to the seat. This results in more control and less wear and maintenance on the valves.
