Q1: What is a grooved butterfly valve with tamper switch used for?

It is mainly used in fire protection and sprinkler piping systems to control water flow and monitor the valve position. The tamper switch helps indicate whether the valve is open or closed.

Q2: Why is a tamper switch important in fire protection systems?

The tamper switch provides valve position supervision. If the valve is closed or moved from its normal position, the switch can send a signal to the fire alarm or monitoring system, helping improve system safety.

Q3: What is the connection standard for this valve?

The valve uses grooved end connections according to AWWA C606. It can be installed with grooved couplings for faster installation and maintenance.

Q4: What material is used for the valve body?

The valve body is made of ductile iron, which provides good strength and durability for fire protection and water piping applications.

Q5: What is the sealing material?

The sealing parts are made of EPDM, which is commonly used for water service and fire protection piping systems.

Q6: What sizes are available?

The standard size range is DN50 to DN200, equal to 2 inch to 8 inch.

For DN50 to DN150, the working pressure is 362 psi. For DN200, the working pressure is 232 psi.

Q8: Can this valve be used outdoors?

Yes. According to the technical data, this valve is suitable for both indoor and outdoor use.

Q9: What standard does this butterfly valve follow?

The valve standard is MSS SP-67, and the grooved end standard is AWWA C606.

Q10: Can you provide technical documents for projects?

Yes. We can provide product drawings, technical datasheets, material information, inspection documents, and other project support

documents according to customer requirements.
