Back Pressure Valves
Help stabilize the downstream pressure and deliver consistent flow |
Griffco Back Pressure Valve는 Diaphragm 방식으로 Anti-Siphon 역할을 할 뿐 아니라 Chemical 공급 펌프에 일정한 압력을 주어 높은 정확성과 공급 시스템의 성능을 향상 시킬 수 있도록 도와줍니다.
Griffco사에서는 다양한 Option의 밸브를 제공합니다.
Valve Features |
• Anti-siphon function
• Solid, robust, machined construction
• Flanged, union, threaded and socket connection options
• Molded Noryl top with integral hardware locking
• 316L SS metal valve and top options
• Molded PTFE/EPDM diaphragm
• Adjustable up to 350 psi (25 bar)
• 4optional pressure ratings (springs)
• Valve sizes from 1/2" to 4" or DN 15 to DN 100
• Tamper-resistant adjustment screw
• High-temperature option up to 300˚F (149˚C)
Griffco Benefits |
• High reliability at affordable price [저렴한 가격에 높은 신뢰성이 장점 입니다.]
• Long diaphragm life [긴 수명을 가진 다이아프램이 장착 되었습니다.]
• Wide range of valve materials [다양한 밸브 재질 선택이 가능합니다.]
• Multiple diaphragm material options [다양한 다이아프램 옵션 선택이 가능합니다.]
