Heavy Duty Shock Absorbing Butterfly Cushion Check Valve

The Dafugui Heavy Duty Shock Absorbing Butterfly Cushion Check Valve is engineered for demanding fluid control environments where frequent pressure variations and high flow velocity require enhanced mechanical protection.

Compared with conventional butterfly check valves, this design incorporates a reinforced valve body, high-strength shaft assembly, and cushioning structure near the sealing area. During reverse flow conditions, the cushion mechanism absorbs part of the disc closing impact, helping reduce mechanical stress on valve components and connected pipeline systems.

The valve supports cast steel, stainless steel, and ductile iron configurations depending on operating pressure, fluid characteristics, and corrosion requirements.

Heavy-Duty Construction & Shock Absorption Design

Reinforced Valve Body Structure

The Heavy Duty Shock Absorbing Butterfly Cushion Check Valve body uses increased wall thickness and optimized casting design to improve resistance against:

Pipeline vibration

Pressure cycling

External mechanical stress

Thermal expansion loads

Critical body areas can be inspected through dimensional verification and non-destructive testing according to project requirements.

Cushion Seat Shock Absorption System

A reinforced cushion structure is installed behind the sealing area to absorb closing impact energy when the disc approaches the seat position.

The cushioning system helps:

Reduce disc seating impact

Lower vibration transmission

Protect shaft and sealing components

Improve operational stability under frequent cycling conditions

High-Strength Shaft and Bearing Assembly

The valve shaft is manufactured from stainless steel materials including 410, 304, or 316 options.

Oversized shaft dimensions combined with PTFE-lined or bronze bushings provide:

Smooth disc rotation

Reduced mechanical wear

Improved resistance against differential pressure loads

Frequently Asked Questions

What maintenance does the internal shock-absorbing cushion require over time?

The cushion zone requires minimal routine care. Inspecting seat seals and shaft packing during scheduled annual plant maintenance turnarounds is typically sufficient.

Does this Heavy Duty Shock Absorbing Butterfly Cushion Check Valve resist high-velocity fluid erosion?

Yes, the internal flow path is streamlined to minimize turbulence, and critical sealing edges can be overlayed with hard-facing alloys like Stellite for severe abrasive conditions.
