L&S-7500 & LS-15000 Distributing Valves
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
