Product Description
The blowdown valve is evolved from the gate valve, which uses the gear rotation 90 degrees to drive the valve stem to achieve the purpose of opening and closing. Fast blowdown valve is not only simple, good sealing, but also small size, light weight, less material consumption, small installation size, especially small driving torque, simple operation, easy to achieve fast opening and closing
The rapid blowdown valve directly relies on the force generated by the medium pressure to help act on the mechanical load on the valve disc. The mechanical load on the valve disc mainly comes from the compression spring, which is almost a fixed mechanical load. Although the blowdown valve loaded by the compression spring can achieve a good seal by adjusting the spring pressure, the seal pressure difference must be strong enough. To ensure sufficient sealing pressure, so as to achieve seal in the normal operation of the valve. The sealing pressure difference should also be less than the opening and closing pressure difference to ensure flexible opening.
Our Advantages
1. Compact structure
The valve body and the valve cover are connected by pinch spoke, compact structure, easy disassembly, easy installation, branch pipe
It is a welded connection.
2. Good sealing using pressure self-tightening sealing structure, sealing ring is made of formed asbestos tray, the higher the medium pressure, the better the sealing.
3. Drain downward
The medium flows into the branch pipe and drains downward.
4. Piston structure
The disc is of movable structure and boronized. Corrosion resistance and long service life

Q3: Details of electric control cabinet
Electric control cabinet adopts PLC touch screen, display in English. It shows working condition details of boiler, such as water temperature, water pressure, exhaust gas temperature, and over-pressure alarm, etc. In addition, the cabinet is used for set up the parameter, record and analyze the operation data, etc.
Q4:What is the using life of your boiler?
1.Normally the boiler is designed for 20 years life span, but with right operation and good maintenance,the boiler can be used for 20-25 years.
