Features & Benefits

SB72 is a kind of high-performance butterfly valve is designed to handle demanding applications where tight shutoff, high pressure, and durability are essential. These valves are commonly used in industries such as chemical processing, oil & gas, HVAC, water treatment, and power generation. High-performance butterfly valves often feature advanced design elements that improve efficiency, reliability, and performance under challenging operating conditions.

A. Packing

The packing is typically made from graphite, PTFE (Polytetrafluoroethylene), or Viton. These materials are selected for their resilience, chemical resistance, and high-temperature tolerance.

B. Seat

The seat is designed to provide a reliable sealing between the disc and the valve body. The seat can be integral (integrated into the valve body) or replaceable. The bi-directional seat could be customized, which provides sealing in both directions, making it versatile for various applications.

C. Disc

The disc has a sealing surface that works in conjunction with the seat to provide a tight shutoff and minimal leakage, especially important in applications requiring zero-leakage performance.

D. Retainer

The retainer helps to maintain the integrity of the seal by ensuring the seat remains in constant contact with the valve body. This ensures consistent sealing, especially under vibratory conditions or in systems with pulsating flows.

E. Body

The body is rigid and designed to handle high-pressure and high-flow applications. High-performance butterfly valves have reinforced body designs to ensure they can withstand challenging conditions without failure. The body may feature a wafer-style design for lighter applications or a double-flanged style for higher-pressure systems.
