High pressure straight flow globe valve (Y type)
Description
Adopt straight flow body, Small flow resistance. 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.
