Brass Lockshield Gate Valve

Meet your go-to solution for secure, tamper-resistant isolation in plumbing, heating or service mains applications. This brass lockshield gate valve features a built-in locking or preset mechanism so once set, the valve remains fixed in position, ideal when you want to prevent unauthorised operation or ensure a fixed flow-setting. The body is constructed in high-quality brass, giving good corrosion resistance and suitability for water systems.

• Pressure rating: PN20 (~20 bar)
• Temperature range: Often given as 10 °C up to +100 °C
• Lockshield feature: A mechanical stop or securing device that locks the valve position after adjustment, preventing movement or tampering.
• Sizes: ½ through 2

Why choose it?

By selecting a brass lockshield gate valve you gain:

• A robust brass construction for corrosion resistance and longevity.
• The lockshield function gives added security and reliability, great in plantrooms, communal areas, or any system where you dont want accidental valve changes.
• The full gate valve style means minimal pressure drop when fully open, yet straight isolation when required.
• Compatibility with standard plumbing threads makes it versatile and freely replaceable in many systems.
