American standard flange plunger valve

The American standard flange plunger valves produced by Shanghai Guanhuan Valve Manufacturing Co., Ltd., UJ41SM American standard flange plunger valves, all adopt the connection of American National Standard (ANSl) and American Petroleum Institute standard (APl), and the operating pressure is between 150LB-300LB

Produced by Shanghai Guanhuan Valve Manufacturing Co., LtdAmerican standard flange plunger valve,UJ41SMAll American standard flange piston valves are connected according to American National Standard (ANSl) and American Petroleum Institute Standard (APl), with a working pressure range of 150LB-300LB. It is installed on the steam pipeline with no leakage at the valve stem, making it the most ideal valve for boiler steam. No fluid loss improves energy efficiency, increases production equipment safety, reduces maintenance costs and frequent maintenance, lowers operating costs, and provides a clean and safe working environment.

【American standard flange plunger valveProduct Features

1When opening and closing the plunger valve, the plunger moves slowly in the sealing ring, and the contact surface is almost not worn.

2The sealing ring adopts a non-toxic new sealing material with strong elasticity and high wear resistance, so the sealing is reliable and durable.

3In the valve, an interference fit is used between the plunger and the sealing ring to ensure the sealing performance of the valve and prevent internal and external leakage.

4When closed, insert the plunger into the lower sealing ring to cut off the flow channel; When opened, although the plunger is detached from the lower sealing ring, it is still hidden inside the upper sealing ring, maintaining isolation from the outside world and preventing leakage.

【American standard flange plunger valveWorking principle

UJ41SMWhen the handwheel rotates, the American standard flange plunger valve drives the plunger to reciprocate up and down in the middle of the hole frame through the valve stem to complete the opening and closing functions of the valve. In the valve, an interference fit is used between the plunger and the sealing ring. By adjusting the flange bolts in the cover, the lateral force generated by the compression of the sealing ring is sealed with the hole surface in the valve body and the outer circle of the plunger, thereby ensuring the sealing performance of the valve, preventing internal leakage, and achieving rapid opening and closing of the valve with a small opening torque. Due to the use of non-toxic new sealing materials with strong resilience and high wear resistance in the sealing ring, it can withstand long-term high temperature and high pressure without losing elasticity, making the sealing performance reliable and durable.
