Detailed Product Description

1)        ZSQF series pneumatic tank valve applies integrated direct flow structure. Its valve body has streamlined configuration without any blocking flow channel. The flow channel internal face is sand-blasted, smooth and wearing-proof, with small flow resistance and with no dead corner. The soft sealing could ensure zero leakage and the hard sealing applies bead-welded Stellite alloy. The product is suitable for work conditions with high temperature or severe conditions containing solid particles. For food processing, the internal face is paved with Teflon without superior corrosive resistance. It meets highest sanitary standards, applicable for conditions with rigorous sanitary regulations in food and beverage industry.

2)        The product provides two structural forms: up-spread and down-spread, which are suitable to different reaction vessel constructions. The nominal through diameter has a scope of DN25~300mm (1"~12), the nominal pressure rating is PN1.6~4.0 MPA (ASME Class:150/300),and the applicable fluid temperature range is -60~450. It is widely used in such sectors including chemical industry, food processing, pharmaceutical, etc. for discharging at reaction vessel bottom.

The product has following characteristics:

1. The valve body applies integrated design and the flow channel uses direct flow without blocking and dead corner and with small flow resistance.

2. The flow channel internal face is sand-blasted, smooth and wearing-proof.

3. The flow channel internal surface is sprayed with Teflon, meeting food-level sanitary requirement.

4. PTFE sealing face ensuring zero leak.

5. Sealing face applies bead-welded Stellite alloy, applicable for severe work conditions including high temperature and solid particles.

6. Hand wheel mechanism available, ensuring productivity even under air source malfunction.
