When used together in grooved piping systems, this power pair combination of the Gruvlok 74-CL coupling and 8700 butterfly valve improves installation efficiency and long-term system performance.
In modern mechanical systems, labor represents the largest variable cost. We believe that true system efficiency is a balance of installation speed and long-term operational performance. Using the Gruvlok 74-CL Coupling alongside the Series 8700 Butterfly Valve helps contractors reduce installation man-hours while also lowering system operating demands.
The 74-CL is shipped ready for install. Do not disassemble the coupling before installation. That step is where much of the labor savings is gained.

Installation Efficiency:
Installed in 6 seconds or less
The 74-CL is engineered with Sabertooth™ Installation Technology, removing the traditional “measure twice, tighten once” slow-down.
- Ready-for-Install Design: No disassembly required. The coupling slides directly onto the grooved pipe end just the way you take it out of the box..
- Tactile Verification: Sabertooth bolt pads provide a physical stop, eliminating the need for torque wrenches or visual guesswork.
- CenterLOK™ Gasket: Features a center pipe-stop rib to ensure proper alignment, helping prevent gasket pinching which is a leading cause of rework.
Install times drop from minutes to seconds per joint. Across a full system, that translates directly into fewer labor hours and more predictable installs.
Operational Efficiency:
Low Torque is the Advantage
While the coupling secures the line, the Series 8700 Butterfly Valve is designed to optimize flow and reduce resistance.
- Up to 39% Torque Reduction: The offset disc design reduces the force required to open and close the valve.
- Reduced Actuator Costs: Lower torque requirements allow for smaller actuators, reducing both upfront cost and energy demand.
- Bubble-Tight Seal (up to 400 psi): Helps minimize internal leakage and maintain system efficiency.
Chemical & Industrial Resilience
For contractors in chemical, industrial, and aggressive environments, material performance is critical. These components are built to handle those conditions.
- Eco Guard™ Coating: A proprietary finish designed to provide strong corrosion resistance in harsh environments.
- Field Serviceability: The Series 8700 Butterfly Valve features a two-piece bolted body, allowing seat or disc replacement without removing the valve from the line.
If you are trying to save time on install and avoid issues later, this is a solid setup. The 74-CL speeds up every connection. The Series 8700 Butterfly Valve lowers operating load. This means faster jobs and fewer problems.
