Description Vendor

The primary product is the Forged gate valves with pressure bonnet Type S43.5, which is a type of industrial valve designed for high-pressure and high-temperature applications. These valves are available in a range of sizes (DN 65-400) and pressure ratings (PN 160-400), with a maximum temperature rating of up to 650°C. The valves feature a forged body and a pressure seal bonnet, ensuring durability and reliability under extreme conditions. They are available with welded or flanged ends, and the design includes a rising stem for easy operation. The valves are constructed from various materials, including stainless steel and other alloys, with options for overlays and specialized components like the wedge, seat, stem, and segmented ring. The product is suitable for applications requiring high performance and precision, with detailed specifications provided for different dimensions and configurations.

Use Cases

  • Power engineering
  • Chemical industry
  • Industrial fluid handling systems

Capabilities

  • Shut-off valve for high-pressure pipeline isolation
  • Supports high-pressure operation up to PN 400
  • Operates at elevated temperatures up to 650°C depending on material
  • Compatible with welded and optionally flanged piping systems
  • Mechanical operation via rising stem design
Vexve Oy Vexve Oy is a manufacturing company specializing in valves for energy infrastructure and is developing hydrogen-ready flow-control solutions. The company’s broader business is based on fluid-control components and application engineering, with equipment selected according to media compatibility, pressure and temperature range, leakage requirements, connection standard, actuation, and the architecture of the surrounding system. The business is mainly B2B and specification-driven, with components selected or engineered to match the operating conditions and standards of the surrounding hydrogen equipment or plant. For hydrogen, the company applies this flow-control expertise to the specific valves, regulators, fittings, manifolds, or related assemblies identified in its hydrogen offering, rather than to hydrogen production as a standalone activity. Its welded ball and butterfly valves can be adapted for hydrogen distribution and sector-coupling networks. The company brings district-energy and gas-valve manufacturing expertise to emerging hydrogen pipeline infrastructure. Within the hydrogen value chain, Vexve Oy therefore serves mainly as a component supplier to equipment OEMs, plant builders, gas-system integrators, test facilities, and infrastructure operators.
