Frequently Asked Questions
A bolted bonnet gate valve has its bonnet (the cover housing the stem and gate mechanism) attached to the body via a bolted flange joint, rather than a screwed connection. This provides a stronger, more reliably sealed joint suited to higher pressure classes and larger valve sizes.
Bolted bonnet joints distribute sealing force more evenly and can be re-torqued or re-gasketed if needed, making them suitable for higher pressure classes (Class 300# and above) and larger bore sizes where a screwed bonnet joint would be unreliable or difficult to seal.
