Description Vendor

The Type S33.4 gate valve, produced by Vexve Armatury, is a specialized industrial yoke gate valve featuring a fabricated body and a solid wedge. These valves are designed for heavy-duty, low-to-medium pressure industrial applications, including power engineering, chemical, petrochemical, and district heating systems.

Use Cases

  • Suitable for hydrogen applications

Capabilities

  • Isolation of flow using solid or flexible wedge gate mechanism
  • Rising stem design enabling visual position indication
  • Fully welded construction for structural integrity and leak-tightness
  • Suitable for high-temperature operation up to 300–400°C (up to 530°C under conditions)
  • Compatible with flanged and welded pipeline systems
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.
