Product introduction

1. Bellows gate valve, the key component of the metal bellows, the lower end and the stem assembly are automatically welded by welding, the upper end and the connecting plate are automatically rolled and welded to form a metal barrier between the fluid medium and the atmosphere to ensure the valve. Zero leakage;

2. Double seal design (corrugated pipe + packing) If the bellows fails, the stem packing will also avoid leakage and comply with international sealing standards;

3. The bonnet has a grease fitting that directly lubricates the stem, nut and bushing, unlike the traditional only lubrication of the thread;

4. Ergonomically designed handwheel for longer life, easy and convenient operation, safer and more reliable;

The bellows gate valve mainly acts as a cutting medium on the pipeline and can be used for full or full closure of different media, but it cannot be used for throttling. The advantage of the bellows gate valve is that the fluid resistance is small, and the torque required for opening and closing is also small; the flow direction of the medium is not limited, and the ring network flowing in the two directions can be used. The structure length is relatively small, which is conducive to pipe installation. In particular, the valve is designed as a double seal of graphite and bellows, which makes the sealing performance superior to ordinary gate valves, greatly increasing the service life of the valve.
