GEOTHERMAL GATE VALVES
SCV Valve
The SCV Geothermal Gate Valves are a purpose-built line of thru conduit and wedge gate valves for the high-heat, high-pressure, abrasive conditions of geothermal power. They are made from materials chosen to resist the silica scaling and impurities in steam, brine, and heat transfer fluids.
The line pairs thru conduit slab and expanding gate valves for full-bore, low-pressure-loss isolation with wedge gate valves for tight steam shut-off, covering production, processing, and injection. Both are proven to operate well above the required 700°F (371°C) specification.
Available in sizes 4″ through 24″ and ASME Class 150 through 900, the valves suit dry steam, flash steam, and binary cycle plants. Thru conduit gates are built to API 6D and wedge gates to API 600, with metal seating, sealant injection, and ISO mounting plates for actuation.
Typical Applications:
Geothermal production wells, injection wells, steam and brine processing, dry steam, flash steam, and binary cycle plants, and high-temperature isolation service.

PERFORMANCE ADVANTAGES
Why the SCV Geothermal Gate Valve Perform Where It Counts
PROVEN ABOVE 700°F
The line is proven to operate efficiently at temperatures well beyond the 700°F (371°C) geothermal specification while holding minimal pressure loss. That gives dependable isolation where the heat of steam and brine defeats standard valves.
RESISTS SILICA SCALING AND IMPURITIES
Materials are selected to resist the silica scaling and inherent impurities in geothermal fluids that cause build-up, leakage, and valve failure. That keeps sealing surfaces working and extends service life in a punishing medium.
FULL-BORE FLOW THAT PASSES SCALE
The thru conduit gate design presents an unobstructed bore when open, minimizing pressure loss and letting scale and solids pass rather than plug the valve. That protects flow and reliability on production and injection lines.
COVERAGE ACROSS THE WHOLE PLANT
Thru conduit and wedge gate designs together handle full-bore isolation and tight steam shut-off across production, processing, and injection service. One qualified line covers dry steam, flash steam, and binary cycle plants.
