  • Field-repairable simple architecture with zero complex parts
  • Negligible flow resistance coefficient during duty cycle
  • Seizure-resistant wedge design unaffected by thermal expansion

Verification before ordering

This page describes a base model configuration. Before purchase, engineering must verify the medium, design pressure and temperature, flow direction, body and trim materials, flange execution, face-to-face dimension and actuator requirements. The published ranges do not mean that every combination of DN, PN, material and temperature is available simultaneously. The exact execution, production lead time and acceptance-document schedule are fixed in the technical quotation. Export projects also require agreement on applicable standards, testing, material traceability and destination-market regulatory requirements.
