The pressure surge has very little operational delay and residual pressure, and there is absolutely no hunting phenomenon!
The "Air-operated Emergency Safety Valve" is a product that opens and closes using an air cylinder. The opening is commanded by a pressure-sensing valve installed on the discharge pipe, which detects subtle pressure fluctuations and abnormal pressures and transmits them to the safety valve. The safety valve is fully opened in response to the opening command, allowing all the liquid in the pump to bypass to the suction side, minimizing external leakage during emergencies. Additionally, the delay in pressure surge activation and residual pressure is very low, and there is no hunting phenomenon at all. 【Features】 ■ Very low delay in pressure surge activation and residual pressure ■ No hunting phenomenon at all ■ Opens and closes using an air cylinder ■ Minimizes external leakage during emergencies *For more details, please refer to the PDF document or feel free to contact us.

Company information
Sanko Engineering has been designing and manufacturing twin-screw pumps, gear pumps, and transmissions for nearly half a century. Pumps are essential wherever fluids are present, not only in the sea, rivers, and lakes but also in factories and facilities. Our company boasts 60 years of experience in producing a wide range of products, primarily focusing on pumps for marine use, both domestically and internationally, as well as land-based pumps. With our experience and technology, we respond to the diverse needs of our customers. In particular, our twin-screw pumps can handle all types of fluids, including chemical heavy oils, and significantly enhance work efficiency with high-performance screw rotors. Our pump products are characterized by reduced vibration and noise, as well as lower pressure burden on the shaft sealing area. Although we are a small company, we strive to provide detailed responses and ensure customer satisfaction.
