The 977HP Oil-Hydrogen Differential Pressure Valve and 977HP Diesel Pressure Regulating Valve are advanced fluid control devices engineered to meet stringent industrial fluid management demands. The 977HP Oil-Hydrogen Differential Pressure Valve maintains precise pressure differences between oil and hydrogen media, critical for applications like power plant turbine systems. Its high-precision mechanism prevents cross-contamination, optimizes efficiency, and enhances operational safety.

The 977HP Diesel Pressure Regulating Valve stabilizes fuel pressure in diesel systems (automotive engines, marine vessels, industrial generators). It mitigates pressure fluctuations from varying loads, ensuring optimal fuel atomization and combustion—boosting efficiency, reducing emissions, and extending engine component lifespan.

Both 977HP series valves feature robust corrosion-resistant construction, suitable for harsh high-temperature/pressure environments. Their compact design enables easy installation in limited spaces, and low maintenance minimizes downtime. Whether for oil-hydrogen balance or diesel stabilization, these valves deliver reliable, industry-standard performance, trusted by engineers and maintenance professionals for durable fluid control solutions.
