The Bray type 41 butterfly valve in lug design is a double eccentric high-performance valve for demanding applications in chemical, energy, industrial plants and high-temperature processes. It offers maximum tightness, fire-safe safety, high pressure and temperature resistance and a durable, low-maintenance design. The Type 41 series meets global standards such as API 609 and ISO 5211 and is ideal for critical applications where absolute reliability is required.
Special features
- Double eccentric design – less seat wear, longer service life
- Lug design (end fitting possible, can be flanged on one side)
- Fire-safe design in accordance with API 607 / ISO 10497
- High-pressure capable: up to PN 40 / PN 64 / PN 100 (depending on version)
- Sealing on both sides at full nominal pressure
- Robust body made of carbon steel or stainless steel
- Stainless steel washer (corrosion and temperature resistant)
- ISO-5211 drive flange for direct automation
- Optional: elastomer, fire-safe or metal seat variants
Advantages
- Excellent for critical media, high pressures and high temperatures
- Long service life thanks to robust metal construction and eccentric kinematics
- Ideal for steam, hot water, oils, chemical media and abrasive applications
- Minimized leakage due to fire-safe seat design
- Low actuating forces → more efficient automation
- Suitable as an end fitting thanks to the Lug design
- Simple integration into automation systems
