Product Description


what is the Grooved Butterfly Valve with Tamper Switch (XD381X-BL) ?What are the materials of each part of Grooved Butterfly Valve with Tamper Switch?

The Grooved Butterfly Valve with Tamper Switch, specifically the XD381X-BL, is a type of butterfly valve designed for use in piping systems, and it includes a tamper switch for monitoring and control purposes. The materials used in the construction of each part of the valve can vary depending on the manufacturer and the specific model. However, I can provide you with a general idea of the typical materials used in the construction of butterfly valves:
1. Body Material:
Common materials for the valve body include cast iron, ductile iron, stainless steel, or other alloys. The choice of material depends on factors such as the type of fluid, pressure, and temperature conditions.
2. Disc Material:
The disc, which is the rotating part controlling the flow, is often made of materials like stainless steel, ductile iron, or other corrosion-resistant alloys.
3. Seat Material:
The seat is the part that forms the seal with the disc to prevent leakage. Resilient materials like EPDM (ethylene propylene diene monomer), Nitrile, or other elastomers are commonly used for the seat.
4. Shaft Material:
The shaft connects the actuator to the disc and is responsible for the rotation of the disc. Stainless steel is a common choice for the shaft due to its corrosion resistance.
5. Tamper Switch Components:
The tamper switch components can vary, but they typically include electronic elements such as sensors, switches, and wiring. The housing for the tamper switch may be made of materials like plastic or metal.

It’s essential to refer to the manufacturer’s specifications or contact the supplier directly to get accurate and detailed information about the materials used in the XD381X-BL model. The choice of materials is critical to ensuring the valve’s performance, durability, and compatibility with the specific conditions of the application.
