Features and Benefits

The top and bottom-guided discs of VERVO globe valves ensure stem operation without experiencing side thrust from high-pressure flow. The non-rotating stem reduces friction among moving components, thereby extending the stem packing lifespan. Consequently, these features enable smooth, effortless operation and reliable sealing even under extreme pressure conditions.

VERVO's proven pressure seal design.
Body-guided disc eliminates side thrust and provides longer disc, seat, and body life.
Impactor handwheel for tight shutoff.
Designed to ASME B16.34.
Body made of superior strength forgings and optional cast steel.
VERVO stem seal offers a tight seal with little to no maintenance over long periods.
Optional live-loading of packing.
Non-rotating stem.
Hardfaced seating faces resist erosion.
Other sizes and pressure classes are available. Contact the company for specifications.

Brief intro

The pressure seal globe valve's middle part incorporates a pressure self-tightening structure, ensuring excellent sealing performance under high pressure and temperature conditions. Typically, the sealing ring is crafted from two materials: low-carbon steel and flexible graphite combined with SS 316. Additionally, the sealing surface is welded with hard alloy, with a post-weld metal layer thickness of 3mm or more, providing superior wear resistance, temperature resistance, and corrosion resistance, thus significantly extending its service life.

Both ends feature a welding structure, with the dimensions of the welding groove customizable according to clients' specifications. Suitable for handling media such as high-temperature and high-pressure water, steam, oil products, and superheated steam, it finds widespread application in thermal power plants, petrochemical industries, metallurgy, and various other industrial sectors.

Main Features

The central connection adopts a pressure self-tightening structure.
The disc and seat are welded with hard alloy.
High-temperature creep resistance design.
The material of the stem is precipitation hardening stainless steel by nitriding.
Operating devices can be manual, gear, bevel gear, and electric actuators.
