Severn's product development manager, Mark Breese, originally challenged the Severn Leeds research and development team to reinvent butterfly valves
to help achieve differentiation and increase market share.
Market outlook of the global butterfly valve
Our range of Butterfly valves
are available in different body materials, with different liners depending on the application.
We started serial production of API 6D valves and butterfly valves
Therefore, either solenoid valves (small volume) or a pneumatic ball or butterfly valve
(large diameter) are ideal.
Because of the lack of failures to the units, the entire system has proven to be both rugged and reliable, including the butterfly valves
themselves, as well as each unit's remote manual override system.
Company offers an inflatable seated butterfly valve
with a highly polished 316 stainless steel housing and disc.
A new butterfly valve
lined with its Teflon NDJ fluoropolymer can serve eight times as long as similar valves lined with a conventionally used material in service with a monomer fluid, reports DuPont.
They include a butterfly valve
or similar disk, a metal plate that acts as a lever, a small air cylinder actuator that serves as the hydraulics assembly, a simple external tension spring that works alongside the air cylinder, and a length of flexible tubing.
The acquisition rounded out Rodney Hunt Co's line of valve products to include Rotovalve cone valves, Streamseal circular and rectangular butterfly valves
, and Howell-Bunger fixed cone valves for energy dissipation.
