Stainless Steel Single Seat Automatic Control Valve for BW / SW / Flange Connection
Self-operated pressure single-seat stainless steel control valve with pilot
General
ZZZYP Series of Self-operated Pressure Control Valve with Pilot does not need any external power source. It is a product that uses power from adjusted fluid and hence regulates itself automatically. The valve uses a regulating mechanism which has the balanced single-seat valve quick flow characteristic. Internally it uses movable components which have no filter and no friction. It has many characteristics including stable fluid pressure; high adjusting precision; could be used to control micro pressure; safe and reliable sealing performance; and can easily be adjusted on the set value during operation. It is widely used for the micro pressure automatic regulation of all kinds of fuel and half-finished petroleum or automatic adjustment on micro pressure of gas and oil tank storage and gas protection (Nitrogen sealing) tank and heat shielding gas protection occasions.
Characteristic:
1. It’s without any external driving energy, and low equipment cost;
2. Simple structure&small maintenance workload;
3. Pressure set point adjustment is convenient
4.Taking pressure from body,and pipeline installation is convenient;
5. Sensitive control&high control precision
