Product Description

PRODUCT INTRODUCTION
There are three type bonnet designs of forged steel flange valves. One is bolted bonnet, the body and bonnet are connected by bolts and nuts and spiral wound gasket. The second one is welded bonnet design, the valve is fully welded and sealed. The third one is pressure seal bonnet, it is pressure seal bonnet construction, and the internal pressure is self-compacting, it normally for high pressure. The seal surface of the pressure seal bonnet forged gate valve is flat or pyramidal and the disc moves in a straight line along the center line of the seat. The stem movement form also has the lifting and rotating stem type for controlling the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.Therefore, this  pressure seal bonnet forged gate valve is ideal for cutting or regulating and throttling.
STRUCTURE OF 2500LB PSB GATE  VALVE

FEATURES
  1. The self-sealing structure can make the valve body of the high-pressure valve and the bonnet connection have a compact structure, saving labor and materials, safe and reliable
  2. When the valve is at 2500LB and above, the stainless steel lining is welded on the contact between the inner cavity of the valve body and the sealing ring, which avoids the erosion of the sealing area of the valve body under the high pressure and the occurrence of pitting leakage, thereby ensuring the valve’s Safe long-term operation
