The sealing surface of a valve is its core component. The leakage forms of the sealing surface can generally be classified into several types, namely, leakage from the sealing surface, leakage from the
Valves are usually connected to pipes in various ways such as threaded, flanged, welded, clamped, and ferrule wafer. So, how should one choose when using and selecting them?
Proper selection and installation of steam traps can prevent freezing as long as there is steam passing through. However, if the steam supply is interrupted, the condensate in the heat exchanger or
I. Testing and Adjustment of Pneumatic Butterfly Valves1. Before leaving the factory, all components of butterfly valves, whether manual, pneumatic, hydraulic or electric, have been strictly debugged.
Pneumatic control valves use compressed air as the power source, a cylinder as the actuator, and drive the valve with the help of valve positioners, converters and other accessories to achieve on-off or proportional regulation.
If you do not carefully check the usage condition and performance specifications of the wafer-type electric butterfly valve before installation, the wafer-type electric butterfly valve may
Electric butterfly valve is a very common pipeline flow regulation device, widely used, involved in many fields, such as the regulation of water flow in the reservoir
Steam trap in the steam heating system plays a role in preventing steam drainage, choose the right trap, can make the steam heating equipment to achieve the highest efficiency.
In the fluid piping system, the valve is the control element, its main role is to isolate the equipment and piping system, regulate the flow rate, prevent backflow, regulate and
1. Valve stem corrosion and protection
Main causes of valve stem corrosion:
The corrosion damage of the valve body is mainly caused by the corrosive medium, and the valve stem corrosion problem is mainly the packing.
