Grease Fitting

Grease Fittings are installed onto the seat and stem of valves. Leakage may occur when the sealed part wears off or for other reasons.

The leakage will be sealed temporarily by injecting the grease through the grease fitting to secure time for remedial measures.

These specialized fittings serve as emergency sealing solutions, allowing operators to maintain system operation while planning comprehensive repairs.

The grease injection process creates a temporary barrier that prevents fluid loss and maintains pressure integrity. Commonly featuring standard Zerk or button-head designs, these fittings accommodate various grease gun attachments for easy field application.

The injected grease fills microscopic gaps and surface irregularities that develop over time due to thermal cycling, mechanical wear, or chemical degradation.

This temporary sealing method is particularly valuable in critical applications where immediate shutdown would result in significant operational losses.

Proper grease selection ensures compatibility with system fluids and operating temperatures for optimal sealing effectiveness.

STRUCTURAL FEATURES

Grease Fitting
Features a top-mounted trunnion fixed support flange or butt welding structure.
 
Allows the sealed metal valve seat to move to the ball, providing two-way sealing of the inlet and outlet.
 
Allows for online replacement of the ball rod, resulting in a longer service life for the metal valve stem seal ring and corrugation, and reduced torque for easy valve operation.
 
The valve does not need to be removed from the pipeline for internal parts repair or replacement.
 
The spherical structure of our valve seat is different from that of ordinary ball valves, allowing for automatic adjustment of the sealing position.
 
Meet the requirements of ISO 5211. The drive device can be assembled at any time according to the different requirements of users.
 
Double blocking and venting, provide an extra level of safety and protection against leaks, particularly in critical applications such as in the oil and gas industry.
 
Ensure precise positioning of the ball.
 
Improve the safety of valve operation.
