Overview: S10 pilot operated safety valve
2、 Detailed information
Product Overview
Pilot operated safety valve is a safety valve that relies on the discharge of medium from the pilot valve to drive or control the main valve. It is installed on pipelines and storage tanks to protect the equipment. When the medium pressure in the equipment abnormally rises to the specified value, the valve automatically opens and then fully discharges, playing a role in protecting equipment safety. This valve has the characteristics of high overpressure accuracy, small opening and closing pressure difference, and strong overpressure discharge capacity.
The design and inspection can comply with standards such as API520, API526, API527, GB/T 28778, GB/T 12241, etc. The fire safety design meets the requirements of API 6FA, and the NACE anti-corrosion and acid resistance are optional.
main features
① Pilot valve controls the main valve with high accuracy

③ The valve seat is soft and hard sealed, with good wear resistance and scratch resistance
④ The action performance and opening height of the safety valve are not affected by back pressure
⑤ Adjustable opening and closing pressure difference
⑥ Can detect the set pressure online
