API 6A Expanding Gate Valves consists of one gate body and related gate segment. The contact surface between are designed to milled V structure.  API 6A Expanding Gate Valves are available in sizes 2-1/16 “through 4-1/16”. working pressure of 2000 psi through 5000 psi.

Parameter of Expanding Gate Valves

API 6A Expanding Gate Valves consists of one gate body and related gate segment. The contact surface between are designed to milled V structure.  API 6A Expanding Gate Valves are available in sizes 2-1/16 “through 4-1/16”. working pressure of 2000 psi through 5000 psi.

API 6A Expanding Gate Valves are commonly used in oil and gas production, refining, and petrochemical industries. These valves are designed to provide a reliable and tight shut-off in high-pressure and high-temperature environments.

Features

The upper/lower roller thrust bearing minimizes operation torque;

Seats can be lubricated from grease injection fitting to reduce abrasion and promote long life;

Non-rising stem design minimize operation space
