Bolted Bonnet Gate Valve (Forged Steel)

A bolted bonnet gate valve made of forged steel is a heavy-duty valve designed for reliable flow control in high-pressure and high-temperature applications. It features a robust construction with a bolted bonnet, ensuring a secure and leak-proof seal between the body and the bonnet. The forged steel material enhances the valve’s strength, durability, and resistance to harsh conditions, making it suitable for demanding environments. The gate valve design allows for full flow with minimal pressure drop when fully open and provides a tight shutoff when closed. Commonly used in industries such as oil and gas, petrochemical, and power generation, this valve is appreciated for its reliability, ease of maintenance, and ability to handle challenging operating conditions effectively.
