Top Entry Ball Valve
Top Entry Ball valves,are used in piping systems where the top of the valve can be removed to gain access to the ball and seats without removing the entire valve from the piping system. Top entry ball valves are typically used in process systems where in-line maintenance is preferred over full valve removal.
- NPS:2″-36″
- Pressure rating:Class150-2500lbs
- Body:Cast steel/Forged steel
- Seat:DEVLON/NYLON/PTFE/PPT/PEEK etc
- ASME B16.34,API6D
NORTECH is one of the leading China Top Entry Ball Valve Manufacturer & Supplier.
-
Double Block And Bleed Ball Valve
The Double Block And Bleed Ball Valve,is designed to replace the complex form of multiple valve connections in pipeline.it utilize a twin-valve design. By combining two valves into one body, a twin-valve design reduces weight and potential leaks paths while meeting the OSHA requirements for double block and bleed.
- Size: 1/2 – 16 Inch.
- Pressure: Class 150 LB – 2500 LB.
- Material: Carbon Steel, Stainless Steel, Alloy Steel, etc.
- floating or trunnion mounted,for the purpose of DBB and DIB.
