Bray has been providing valves and actuators for the power generation industry for over 30 years, whether it be for steam isolation, steam drain and venting, boiler feedwater, cooling water, fly ash, soot blowers, fuel oil, natural gas, geothermal, heat exchanger check and isolation, heat transfer fluid, wet flue gas desulfurization, water treatment or utilities.
Reliable and low-maintenance operation is critically important in power plants, and that is where Bray offers a clear advantage over competitors. Bray has the scope of valve products to address the variety of applications, valve types, sizes, pressure and temperature ratings, materials, and features commonly required in today’s power plants and emerging power generation technologies.
Bray provides a one-source solution for automated emergency block valves and safety instrumented systems as well as process control using smart technology for diagnostics and preventative maintenance. Make Bray your global flow control partner for the Power Industry.
Double offset butterfly valves
The Bray/McCannalok series offers rugged reliability in a proven design. Large diameter Bray resilient seated butterfly valves have the same beneficial design features as the smaller diameter valves.
The internal disc-stem drive connection eliminates exposed retaining hardware and the seat completely isolates the valve body & stem from the line media. This dry body and stem (shaft) design is important for preventing internal corrosion and is particularly beneficial for power plants that use seawater for the circulating water service.
Steam drain and vent
Triple offset butterfly valves
One of the primary concerns of the industry is safety, and rightfully so, especially in a nuclear plant. The industry needs reliable, proven valves that limit or extinguish the potential for hazardous situations. Bray valves are designed for just that.
Bray/McCannalok and Tri Lok high performance valves are engineered to perform under the harshest conditions of the industry and can be relied upon to deliver dependability, versatility, and reliability at the most affordable price available.
High pressure, high temperature requiring tight shutoff metal-to-metal seating
Natural gas shutoff
Critical ESDV and BDV
The strength of Bray valves
Part of the strength of Bray valves is that they offer both resilient seated and metal seated designs that provide zero leakage. Both McCannalok double offset and Tri Lok triple offset butterfly valves are factory tested with both high pressure (at 1.1 times rating) water and low pressure gas for bi-directional zero leakage shutoff. Bray Flow-Tek M4 severe service ball valves with all-metal seats are tested to zero leakage for turbine water induction prevention, superheater drains, inlet/outlet drains, high point boiler vents, boiler blowdown isolation, main steam stop valves, and other critical services. All stem designs incorporate a blow-out proof feature.
