Product Description

Waits Valve Bronze Wafer Butterfly Valve is commonly used in fire protection systems as a system control valve and zone valve. It uses automatic roll welding technology to form a metal barrier between the fluid medium and the atmosphere. Waits Valve is equipped with a slow-closing handwheel-operated gearbox to reduce the risk of water hammer.
It uses a bellows structure inside: the lower end of the stainless steel bellows is welded to the valve stem to prevent process fluid from eroding the valve stem; the other end of the bellows forms a static seal between the valve body and the bonnet. This double seal design ensures that even if the bellows fails, the valve stem packing can still effectively prevent leakage. The bellows are welded to the valve stem to maintain stable operating performance and avoid valve stem vibration caused by valve core movement. This valve is ideal for pipelines that carry steam, flammable and explosive materials, thermal oil, high purity and toxic materials.

Features
All valves are equipped with a built-in pre-wired monitoring anti-tamper switch assembly. The anti-tamper switch will send a signal that the valve disc has moved from the fully open position.
Pressure range:
CL125~CL150 PN6 ~ PN16
Size:
NPS 2″~ NPS48″ DN50~ DN1200
All valves are equipped with anti-tamper switch assemblies,
suitable for indoor and outdoor use.
With slow closing and slow opening functions, it can prevent easy damage
The Waits Bronze Wafer Butterfly Valve offers simple and compact construction, featuring a small size, light weight, and minimal components for easy installation, disassembly, maintenance, and installation in any position. Its easy operation allows the disc to rotate 0°-90° around the axis for quick opening/closing with just a 90° turn, providing excellent fluid control characteristics.
With reliable sealing performance, it uses soft sealing typically rubber or other elastic materials embedded around the disc or in the valve body to ensure tight closure, making it suitable for various media, especially in high seal demand applications.
Crafted from aluminum bronze, it boasts corrosion resistance, ideal for pipelines with corrosive media like seawater, acids, and alkalis, extending the valve’s service life.
Its wide applicability enables use in harsh conditions such as desulfurization, vacuum, and seawater desalination systems through material choices (e.g., different disc and seat materials) and pinless disc-shaft connections.
