Engineered Strength Through Forging: Electric Motor Operated Gate Valve
At the core of Shoritsu Seisakusho’s manufacturing philosophy lies the forging process—a method that eliminates internal voids in metal, refines grain structure, and maximizes material integrity. This process ensures:
Superior mechanical strength and durability under demanding conditions
High resistance to fatigue and bending stress, critical in pressurized systems
Extended operational lifespan through metallurgical uniformity
Forged valves such as the Shoritsu Electric Motor Operated Gate Valve are ideal for power generation, chemical plants, and high-pressure gas equipment—where precision and endurance cannot be compromised.
Precision-Controlled Flow with Electric Operation
Equipped with a high-torque electric actuator, this valve enables precise remote operation and modulation. Whether in energy plants, petrochemical processing, or automated production lines, the valve’s gate-type design ensures:
Tight shutoff performance
Low pressure loss
Smooth linear flow control
Its motorized actuation minimizes manual intervention, improving plant safety and reducing maintenance downtime.
Built for Demanding Applications
Shoritsu’s electric gate valves are manufactured under ISO 9001-certified quality systems and approved by Japan’s Ministry of Economy, Trade and Industry for high-pressure gas applications. Key advantages include:
Pressure ratings up to Class 4500
Materials including forged carbon steel, stainless steel, and low-alloy steel
Tested for pressure integrity and leakage resistance following JPI and API standards
Such reliability has earned Shoritsu Seisakusho a strong reputation in industries such as petrochemicals, energy, and industrial gas processing.
Why Choose Japanese Forged Valve Technology
Japanese manufacturing standards emphasize continuous innovation and total quality management. Shoritsu’s integration of cutting, forging, machining, assembly, and inspection in one production line guarantees consistent product quality and traceability—key expectations for engineers and industrial buyers worldwide.
Conclusion
The Electric Motor Operated Gate Valve by Shoritsu Seisakusho is more than just a valve—it’s an assurance of safety, performance, and Japanese precision. Designed for high-demand environments, it stands as a trusted choice for modern facilities seeking automation-ready solutions built to last.
