SAZ Orion PO Conventional Pilot Operated
SAZ Orion PO Conventional Pilot Operated gas lift valves are used in Intermittent flow gas lift application. Orion PO are installed on tubing retrievable gas lift mandrels. These valves are available in either nitrogen charged or spring-loaded options. The spring loaded valve has a pilot section which contains a bellow assembly, spring, stem and seat that controls the opening and closing of the main power section. The spring provides the closing force that acts on the pilot valve stem. When injection gas pressure and production pressure exceeds the spring force, the pilot opens and applies pressure to the main power section. The piston in the power section shifts open to expose a very large port, allowing rapid injection of a large volume of gas into the tubing. The spread can be adjusted by changing pilot valve stems and seats.
