Pig Valve
Pig Valve

Pig Valve is one of the most proud main product of Dipper Valve. As the professional device to cleaning,separating transportation,different diameter pipe pigging,switching and transportation,protect inner floating proof tank,pig valve has showed its huge value in application as well as advantage in comprehensive cost/performance ratio at the application which required launching or receiving pigs. At the time,Dipper Valve has create this detail market, it is also established its leading position with piles of unique honours. Besides of bypass pig valve,cleaning pig valve and separating pig valve,we also supply different diameter pig valve,three way pigging valve these with Dipper Valve patent products.

ESD Valve
ESD Valve

The emergency shutdown valve it is an essential safety protect device working at petroleum and natural gas well site. It is aims to reliable shutdown natural gas, regulator station, long transmission pipe transportation,so that protect pipeline and equipment safety running. When system pressure higher than the highest limitation or lower than the lowest limitation,the valve will automatically closed to prevent natural gas (medium) leakage. Dipper Valve can provide ball valve type ESD valve as well as global type ESD valve according to different application to safety protect wellhead, station and equipments.

NDIV Rising Stem Ball Valve
NDIV Rising Stem Ball Valve

The NDIV rising stem ball valve is a non friction and low torque ball valve which utilize the stem to control the core tilting and rotation.since the birth of this kind of valve,with its non friction and low torque advantage,it is widely applied to sever application where big differential operation pressure happens,frequently operation,pressure and temperature request valve in good sealing at long term or not allowed downtime maintenance or replace valve application, such as petroleum, chemical,city water supply and drainage application. The NDIV Rising Stem Ball Valve has successful passed national localizing manufacturing project verification,it is manufactured by multiple independent intellectual property rights,it is a reliable product to serve application ,and provide reliable service capability.

Automatic Recirculation Valve
Automatic Recirculation Valve

The centrifugal pump normally are working under changeable flow rate,when the centrifugal pump working under low load,the overheating,serious noise,unstable working and cavitation erosion which may damage the pump could happen.The automatic recirculation valve is a minimum flow control valve to maintain centrifugal pump required minimum flow rate,it is a device to protect the centrifugal pump in good working,Dipper Valve automatic recirculation valve with:flow rate sense , re-circulation control,bypass multi-level pressure relief as well as prevent backflow function,it is a reliable choice to prevent centrifugal pump.
