Description Vendor

Type S33.6 through-conduit gate valves are high-performance, industrial isolation valves designed for full-bore flow, making them ideal for long-distance pipeline systems transporting water, oil, gas, and non-corrosive liquids. They are specifically designed for pigging operations and are manufactured according to API 6D standards.

Use Cases

  • Suitable for hydrogen applications
  • Long-distance pipeline systems

Capabilities

  • Provides full-bore flow with flow resistance equivalent to pipeline
  • Operates in pressure classes Class 150–600
  • Supports pipe sizes NPS 4–48
  • Enables double block and bleed (DBB) functionality via seat design
  • Allows automatic pressure relief from body cavity to piping
  • Compatible with manual, electric, and pneumatic actuation
  • Designed for horizontal pipeline installation with vertical actuator orientation
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.
