Features and Benefits

The VERVO globe valve features a top and bottom-guided disc design that ensures smooth stem operation, free from side thrust induced by high-pressure flow. With a non-rotating stem, friction among moving components is reduced, leading to extended stem packing life. These design elements culminate in effortless operation and reliable shutoff even under the most demanding 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.

The central component of the pressure seal globe valve incorporates a pressure self-tightening structure, ensuring optimal sealing performance even in environments of high pressure and temperature. Typically, the sealing ring is available in two materials: low-carbon steel or a combination of flexible graphite and SS 316. Additionally, the sealing surface is fortified with hard alloy through welding, creating a metal layer with a thickness of at least 3mm. This construction imbues the valve with exceptional wear resistance, temperature resilience, and corrosion resistance, significantly extending its operational lifespan.

Both ends of the valve feature a welding structure, with the dimensions of the welding groove customizable according to client specifications. This valve is suitable for handling various media, including high-temperature and high-pressure water, steam, oil products, and superheated steam. Consequently, it finds widespread application across industries such as thermal power plants, petrochemicals, metallurgy, and other industrial sectors.
