Grooved Gate Valve —
Non-Rising Stem, Grooved End, DN50–DN300
The CA-FIRE grooved gate valve brings the reliability of a full-bore, resilient-wedge non-rising stem gate valve to grooved-end piping systems. Roll-grooved ends on both sides accept standard Victaulic-style mechanical couplings, allowing fast bolt-free installation and easy in-line removal for maintenance — with no welding, no flange alignment and no special tooling. Available in DN50–DN300 (2" – 12"), the grooved gate valve is designed for fire sprinkler branch mains, cross mains and system risers where grooved piping is the specified connection method.
What Is a Grooved Gate Valve?
A grooved gate valve is a gate valve with roll-grooved pipe ends machined to ANSI/AWWA C606 dimensions instead of traditional flanged ends. The grooves engage standard mechanical grooved couplings — such as Victaulic-style rigid or flexible couplings — to form a secure, pressure-rated joint without bolting flange faces together.
The grooved connection method has become the dominant choice for fire sprinkler pipework in North America, the Middle East and many international markets because it reduces installation time by up to 60% compared to flanged connections. The grooved gate valve combines this fast-assembly connection method with the full-bore, low-pressure-drop flow characteristics of a traditional gate valve, making it the preferred isolation valve on grooved fire protection systems.

Grooved Gate Valve Key Features
Fire Protection Applications
Fire Sprinkler System Branch & Cross Mains
The grooved gate valve is the standard isolation valve for branch mains and cross mains in fire sprinkler systems where grooved piping is specified. Installed fully open, the valve provides zone-by-zone isolation for maintenance and system modifications without shutting down the entire system — and reinstalls as quickly as it was removed.
System Riser Isolation
Used on fire sprinkler system risers in commercial, residential and industrial buildings where grooved-end piping is used from floor to floor. The compact non-rising stem profile suits riser cupboard installations where space around the valve is limited. The dial indicator confirms valve status without requiring the engineer to operate the valve.
Standpipe & Hose System Connections
Suitable for standpipe and hose systems in buildings with grooved piping, where the valve provides branch isolation for individual floors or hose cabinet connections. The fast-release grooved coupling makes system expansion or zone additions straightforward.
Retrofit & Refurbishment Projects
The grooved gate valve is an ideal choice for system upgrades and refurbishment projects where existing flanged valves are being replaced with grooved-piping systems, or where grooved fittings are being introduced to an existing installation. The ability to install and remove without welding or cutting pipe makes it highly practical in occupied buildings.
Grooved vs. Flanged Gate Valve — Connection Comparison
| Grooved Gate Valve | Flanged Gate Valve | |
|---|---|---|
| Installation method | ✅ Grooved coupling — bolt-free, no welding | Bolted flange — alignment required |
| Installation speed | ✅ Fast — couplings seat in seconds | Slower — multiple bolts per joint |
| Valve orientation | ✅ Rotatable before coupling tightened | Fixed — flange bolt pattern locks position |
| In-line removal | ✅ 2 bolts — valve out in minutes | All flange bolts + pipe movement required |
| Best for | Grooved piping systems, confined spaces, retrofits | ✅ High-pressure or large-diameter mains, DN350+ |
Frequently Asked Questions — Grooved Gate Valve
-
Q1 What is a grooved gate valve?A grooved gate valve is a gate valve with roll-grooved pipe ends instead of flanged ends. The grooves accept standard Victaulic-style grooved mechanical couplings, allowing the valve to be installed and removed without welding or bolting flanges — significantly reducing installation time on fire sprinkler and standpipe systems. The valve body and internal mechanism are identical to a conventional gate valve, providing full-bore flow with negligible pressure drop.
-
Q2 Is the grooved gate valve compatible with Victaulic couplings?Yes. CA-FIRE grooved gate valves are machined to standard roll-groove dimensions conforming to ANSI/AWWA C606, which is the same standard used by Victaulic and other major grooved coupling manufacturers. The valve will accept Victaulic-style and equivalent grooved mechanical couplings across the full DN50–DN300 size range.
-
Q3 What is the difference between a grooved gate valve and a flanged gate valve?A grooved gate valve uses roll-grooved ends and mechanical couplings — no bolt holes, no gasket alignment and no welding required. This makes installation and removal significantly faster and allows the valve body to be rotated for access before the coupling is tightened. A flanged gate valve uses bolted flange connections that are better suited for very high-pressure service or large-diameter mains (DN350 and above). For fire sprinkler systems where grooved piping is specified, the grooved gate valve is the practical choice.
-
Q4 What sizes does the CA-FIRE grooved gate valve come in?The CA-FIRE grooved gate valve is available in DN50–DN300 (2 inch to 12 inch), covering the standard size range for fire sprinkler branch mains, cross mains and system risers. For larger-diameter mains or flanged piping systems, see our OS&Y flanged gate valve in DN50–DN400.
-
Q5 Can the grooved gate valve be fitted with a tamper switch?Yes. The CA-FIRE grooved gate valve can be fitted with a supervisory tamper switch to send an electronic signal to the fire alarm control panel when the valve is moved from the fully open position. CA-FIRE also offers a dedicated gate valve with tamper switch with integrated supervisory monitoring for installations requiring electronic valve supervision.
