Valves - WHEATLEY Dual Plate Wafer Check Valve
設計特點
惠特利的車身設計提供了以下功能：
• 緊湊晶圓一體式的設計風格
• 中心職位支持沒有外部的內(nèi)部程序集
針腳或插頭
• 由于惠特利，確保無滲漏到 atmoshere 的標準
它消除了通過孔和管道的設計插頭在正文中
• *大流通面積減到*小的壓力損失
• *大程度減少安裝空間和時間
雙板設計生產(chǎn)*大強度的*低開啟和關閉時間
夾緊板提供額外的閥板的強度和允許密封件可以方便地更改
專門設計的平面、 完整的聯(lián)系密封件保持積極關閉在低工作壓力。與大多數(shù)其他閥門，不同的是這些封印很容易被取代在字段中
扭轉(zhuǎn)彈簧協(xié)助防止流逆轉(zhuǎn)的閥板封閉。一致閥門的反應可確保針對砰和水擊
重型耐腐蝕建設軸
軸支持作為停止以防止閥板的旅行。耐腐蝕與大軸軸承表面。輕松地可移動內(nèi)部裝配、 維修或更改

Liquids 15 feet per second
Gases 100 feet per second
Valves - WHEATLEY Series 500 Fire Tested Carbon Steel Flanged End Check Valve
API 6D/Drilling production valve carbon steel flanged end check valves
When you need a check valve that has to work!
Features:
• 316 stainless steel trim is compatible with a broad range of
media and operating conditions
• Full-Open, through-conduit design for low pressure drop and
less turbulence.Valves easily pass pigs and spheres
• 90 Durometer, peroxide-cured seals are compatible with a
broad range of media and operating conditions. Seals provide
a bubble-tight shut-off every time
• Suitable for vertical flow up or horizontal installation.
Eliminates installation guesswork
• All materials conform to NACE MR0175 / ISO 15156
• Cast on flanges provide greater valve body integrity and
fewer leak points
• API 6D Monogram (510 / 511 Only)
| API 6D/Drilling production valve carbon steel flanged end check valves Features: |
• Valve is fire tested to API 6FD requirements (except for 1 in. (25 mm) valve)
• CANADIAN REGISTRATION NUMBER (CRN) available upon request
• Flanges are back-faced - an extra manufacturing step which provides smoother bolting surfaces and
even bolt loading
• Bolted top entry complete with 1/2 in. NPT cover tap for gauges and accessories (except 1 in. (25 mm) size)
• In-line repairable
• Thru-pin clapper shaft makes clapper removal easier and extends valve life by transferring wear and tear to
an inexpensive replaceable part.
