High pressure straight way globe valve
Description
Adopt straight way body, there are three kind of body, die forging, free forging and casting.
Pressurized seal design, more reliable the seal.
The connection between the stem and the disc is kinetic, good concentric.
The sealing surface is welded with hard alloy. Wear resistant and corrosion resistant, reliable sealing, long service life.
Stem adopt 38CrMoAlA or SS specified by customer, heat treatment, surface treatment.
Drive mode: manual, electric, pneumatic, hydraulic, gear transmission, worm drive.
