Stainless Steel Globe Valve


Description of Stainless Steel Globe Valve:

The principle of ZECO stainless steel globe valve is that through the drive mechanism to make stem and wheel-nut to make the relative rotation, stem drive Piston to make up and down movement along the axis, play a role in switching. The sealing is done by stem and wheel-nut make mutual pre-tightening force role in the overlay Piston and seat sealing face. According to the location of the stem, thread can be divided into two types: up thread stem and down thread stem. Up thread stem: stem thread is outside of the medium, the stem erosion from the medium, easy lubrication. Down thread stem: stem thread in the valve body, in direct contact with the medium, the stem is east to erosion by medium, no lubrication.


Features of Stainless Steel Globe Valve:

1. ZECO stainless steel globe valve is opened or closed in the process, the movement travel of the valve disc is small, so the opening and closing time will be shortened compared with the gate valve, the valve height will be much shorter, but the structure length will be longer;

2. The sealing surface of ZECO stainless steel globe valve is not easy to be worn and scraped, because the sealing surface of globe valve disc and valve seat are sealed by rigid torque of valve stem, and there will not be mutual friction contact for a long time like a gate valve, so the globe valve has a longer service life and does not need long-term maintenance to maintain the normal operation of the valve;

3. ZECO stainless steel globe valve is a simple structure, easy manufacturing, and maintenance;

4. The stem of ZECO stainless steel globe valve is designed in anti-blow-out stem conical backseat surface to permit repacking of valve in the fully open position.
