**Title:** Fire Gate Valve for Electric Actuator Type 47GVA (Flanged, with Rubberized Wedge)

**Description:**

Fire wedge gate valves type 47GVA have both a mandatory certificate of compliance with the requirements of the Technical Regulations on Fire Safety TR EAEU 043/2017 and a voluntary fire certificate.

A voluntary certificate confirms the quality of the goods to established state standards, but its execution is not due to the requirements of the law, but as a result of the manufacturer’s own initiative. A mandatory certificate is required for certain groups of goods for which Russian laws establish a requirement to confirm their quality.

Fire wedge gate valves type 47GVA are widely used in automatic water and foam fire extinguishing systems. Gate valves used in fire extinguishing systems are painted red in accordance with legal requirements.
