Lug Type / Wafer Type

Valve body

ES Valve V-Type 1000/2000 Series High Performance Double Eccentric Butterfly Valve are designed 100% compliance with API 609 and ASME B16.34. Utilizing PTC Creo Parametric (Pro/E) Computer-add-design in every component and result in best reliability.

Top Mounting

Compliance with ISO 5211. York designed with draining system for outdoor service.

Anti-Blow-out Stem and Anti-Electrostatic System

An anti-Blow-out design and optional Anti-electrostatic system. Compliance with API 609 and ATEX.

Valve Disc

Valve disc uses stainless steel with computer-add PTC Creo Parametric software to analyze stress performance to achieve API 598. Based on advanced 3D CAD simulation, ES Valve developed a streamlined disc with lower noise and turbulence. Meanwhile, all our disc’s and stem’s surface are hard-chrome-plated. This feature significantly enlarges disc performance of anti-rubbing and anti-shocking, which result in better life cycle.

Patented Retainer Ring

A no-screw-floating design to elimate cold flow. This design provides positive tight shut-off of seat. Surface roughness is 125-200AARH.
