Baode corner seat valve product sales principle parameter description

Cape Verde seat valve
The regulator gas used in the BURKERT angle seat valve is supplied by a small direct-acting pressure reducing valve. If the small direct acting pressure reducing valve is installed inside the valve body, it is called the internal pilot type pressure reducing valve; if the small direct acting pressure reducing valve is installed outside the main valve body, it is called the external pilot type pressure reducing valve. . Originally imported German Baud BURKERT angle seat valve structure, compared with the direct-acting pressure reducing valve, the valve increases the nozzle baffle composed of the nozzle 4, the baffle 3, the fixed orifice 9 and the air chamber B to enlarge Link.
BURKERT 2000 series for medium zui high temperature +180 ° C

Cape Verde seat valve
The Baldor 2000 external pilot control angle seat valve is driven by a single-acting or double-acting piston actuator. The actuator is available in two materials for different ambient temperatures. Gunmetal or stainless steel two-way valve body, large flow.
Reliable self-adjusting packing seals provide high sealing. This maintenance-free, durable valve adds a variety of accessories for position indication, travel limit or manual switch.

Cape Verde seat valve
The structure of the BURKERT angle seat valve, compared with the direct-acting pressure reducing valve, increases the nozzle baffle enlargement of the nozzle 4, the baffle 3, the fixed orifice 9 and the air chamber B. When the distance between the nozzle and the baffle changes slightly, the pressure in the B chamber changes significantly, causing a large displacement of the diaphragm 10 to control the up and down movement of the spool 6 to advance The valve port 8 is opened or closed to increase the sensitivity to the spool control, that is, the voltage regulation accuracy is improved.
