Bray Series 40-45 Butterfly Valve: Proven Performance for Snowmaking

Built for Abrasive Water

The UHMWPE seat is the key factor. Ultra High Molecular Weight Polyethylene resists abrasion far better than typical rubber seats. In systems where sand or debris is present, that matters. Instead of cutting into the seat over time, particulates are less likely to damage the sealing surface. That directly impacts how long the valve maintains shutoff.

Bubble Tight Shutoff

Zero leakage. For real. The seat design and sealing geometry are built to maintain tight shutoff even after extended cycling.

Internal and field testing have shown performance beyond 100,000 cycles while maintaining seal integrity. There is also a high-cycle configuration tested up to 1 million cycles for operations that demand it.

Why Snowmakers Pay Attention to the Seat

Seat material is usually where valves fail first in snowmaking systems. The Series 40-45 uses a UHMWPE seat that does three important things:

• Resists abrasion from sand and silt
• Handles chemical exposure in treated water
• Maintains sealing performance in cold environments

It also encapsulates key internal components, helping protect the body and stem from direct exposure to water. That reduces corrosion and extends service life.

If you have had valves start leaking mid-season or struggle to hold pressure, this is typically where the problem starts.

Designed for High Pressure

This is a double offset, high performance butterfly valve. The sealing system is pressure-assisted. As line pressure increases, the seal tightens. That matters on the mountain where pressure fluctuations are constant. You are not relying on a static seal. The valve uses the system conditions to improve performance.

Wafer Style Advantages on the Mountain

The wafer body design keeps things simple.

• Installs between two flanges
• Reduces weight compared to heavier valve types
• Saves space in tight valve pits or mechanical areas

For snowmaking infrastructure, especially in retrofits or constrained installations, that matters. Less weight and simpler installation can make a difference during short maintenance windows.

Reliability in Cold, High-Cycle Operation

Snowmaking systems do not run once and sit idle. Valves open and close repeatedly throughout the season. The Series 40-45 is built for that kind of use.

• High-strength through-stem design
• Rugged body construction
• Proven long-term cycle performance

This is not a light-duty valve adapted for snowmaking. It is a high performance valve applied in a demanding environment where durability is required.
