Petroleum Hemisphere Valve, Chemical Gas Special Valve

Structural features:<ul>
A special seat design structure, two-way seal
Eccentric structure, open valve core and valve seat separated from flow channel straight through, does not appear card blocking phenomenon
Double eccentric spherical seal structure with cam wedge clamping effect between seal pair with automatic compensatory, safety and reliable
Opening moments of seal pair completely out of protection seal pair abrasions, to extend seal vice lifespan
Switch light: opening and closing torque is small, flexible rotation and shearing action of valve core and valve seat can cut open and close when sealing surface fouling and adhesion material, tight and reliable seal
Valve is hard seal structure, sealing according to various media, use of wear-resistant alloy material, so that valve has a hard, wear resistant and corrosion resistant
When valve opens, fluid does not directly washed spool valve and long service lifespan</ul>
