Product Description

Flanged ends Forged Gate Valves

CHAODA Valves Group is specialized in manufacturing Flanged ends Forged Gate Valve with following good characteristics: good sealing performance, reliable safety guarantee, long life span and etc.

When Flanged ends Forged Gate valve is opening, the passage is fully opened when the lifting height of gate is the same with valve diameter. However, the posion of disc could not be seen in fact, so the stem height is regarded as the opening indicator for the valve. That is to say, the position where the stem cannot be moved anymore is the fully open position for the valve. But actually, we regard the position where the stem cannot be moved anymore and move back 1/2 or 1 turn as the fully opening position to avoid the lockhole phenomenon caused by temperature fluctuation.

Flanged ends Forged Gate Valve product description

Flanged ends Forged Gate Valve are suitable for using on various kinds of pipeline from Class150 To Class900, DN15 To DN50 to cut off or connect the flowing of medium. By using different material, the valves could be suitable for medium such as water, steam, oil, nitric acid, acetic acid, oxidizing substance, carbamide and etc. 

All our Flanged/Threaded/Socket welding Ends Forged Gate valves have the back seating design. In most cases, the carbon steel gate valve is fitted with a renewable back seat. For stainless steel gate valve, the back seat is machined directly in the bonnet or is machined after welding. When the gate valve is at fully open position, the sealing of the back seat can be very reliable. However, as per the requirement of API 600, it is not advisable to add or change packing by the mean of back seating when the valve is pressure containing.
