L&S-7500 & LS-15000 Distributing Valves

LS7500 Distributing Valve

The L&S-7500 and the L&S-15000 Distributing Valves with high flow capacity are specifically designed to work with Hydroelectric turbine governors of low to medium operating pressure.


L&S Electric has digital governor upgrade solutions with everything needed to upgrade any governor into a new high-performance digital governor: from a pre-engineered package for a cost-effective and expedient upgrade to custom solutions for the most demanding plants.

  • Higher performance than mass-produced two stage valves
  • Fast response with zero lap valve performance
  • Cost-effective spare parts
  • Compact design allows for optimum mounting
  • Works with both Low-pressure and High-pressure systems

Features

  • Frequency response 4-5 times faster than old mechanical and analog governor systems
  • Maximum flow adjustment via solid locking nuts
  • Valve porting can be specified to accommodate pressure and flow needs
  • “A” and “B” ports (open and close control ports) can be reversed in the field if necessary
  • No external pinch points
  • SAE outlet ports
  • When used with Universal Pilot Control Manifold (as shown in pictures):
  • Duplex pilot valve filtration with dirty filter indication (visual and electrical)
  • “O” ring sealing for leak free operation
  • Shutdown verification contact
  • Clean oil pressure source for auxiliary use
  • Pressure supply “OK” contact

  • Safety shutdown systems:
  • Local, manual shutdown valve
  • Proportional valve shutdown upon power loss
  • Fail-safe de-energize to shutdown solenoid valve
  • Energize to shutdown solenoid valve
  • Pilot-operated latching hydraulic circuit

Specifications

Pressure range: up to 1500psi for L&S-7500, and up to 1100psi for L&S-15000
