I. Product Overview and use:
In this system, the butterfly valve system is used to remove internal and external advance branch, according to GB/T-12238-2008,
GB/T26640-2011 standard, designed for flange type; In particular, the rear seat ventilation structure is used, whether at low temperatures or I. Product Overview and use:

This product is the introduction of foreign advanced branch technology, specially designed for RTO exhaust gas treatment storage furnace outlet control valve, referring to JB/T8692-1998, GB/T14478-2012, SH3531-1999 and other standards and high temperature valve thermal expansion and contraction data, designed for flange type, And enjoy the patent certificate ZL2016 2 0637602.2. All materials are made of high quality heat-resistant steel and butterfly plate, valve shaft inner parts are imported 310S, nickel-based superalloy, patent ultra-high temperature special steel, and the body is designed with high temperature resistant materials; The valve is designed as a straight through type, the flow is too large for easy adjustment, with its own unique design of two shaft end cooling, advanced technology, reliable quality; No matter under any high temperature conditions, there is no stuck phenomenon, and the advantages of flexible opening and closing are as follows. It is more suitable for regulating the gas flow and opening and closing in the pipeline system such as hot air volume regulation and environmental protection. It can be installed in any position, and can also realize the requirements of field operation and remote centralized control. It is an ideal valve for high temperature fluid regulation and control, and has been well received by the majority of users.

Ii. Main performance specifications:

1. Nominal effective diameter: DN×DN 200×200-1600×1600

2. Nominal pressure: PN 0.5bar

3. Strength test pressure: PS 3.0bar

4. Applicable temperature: t ≤1260℃ Special up to 1400℃

5. Leakage rate: ≤1.5%

6. Applicable medium: hot gas; Containing dust and high temperature gas, exhaust gas, etc.

7. Medium flow direction: any direction

8. The control form of the medium: fully open. Full and free adjustment in the range of 0 ~ 90º

Iii. Characteristics and Standards:

1. The valve is welded with high quality heat-resistant steel plate, small and light, easy to decorate, and high temperature resistance, corrosion resistance; It is a reliable product in actual production at present.

2. Because the butterfly plate adopts the center line vertical structure, the flow area is large, the flow resistance is small, the switch is flexible, the operation is convenient, the time saving and labor saving.

3. The temperature of the valve is too high, and the head and tail are equipped with heat dissipation devices to ensure flexible steering.

4. Welding data: according to GB/T5185-2005 GB/T19866-2005.

5. Manufacturing and acceptance for the enterprise standard TOD/S1609-2016, and JB/T26480-2011 regulations, the allowable leakage ≤1.5%, in line with JB/Z248-1985 standards.
