Description
National Eaton Water Valve Kit
Part # 6330030
Eliminate dripping, water loss, and inaccurate ingredient mixing by rebuilding your hot drink center with the National Eaton Water Valve Kit (Part # 6330030). In commercial coffee machines like the popular National 673 and 677 series, water valves undergo heavy heat and high-volume cycles. Over time, internal mineral buildup and rubber degradation lead to stuck valves or low water pressure, directly ruining drink quality.
Instead of replacing the expensive entire valve block assembly, this complete Eaton-style rebuild kit gives you all the necessary wear-and-tear components to restore factory-fresh sealing and performance. It ensures your machine dispenses the exact programmable water volume required for flawless fresh-brewed coffee, hot chocolate, and gourmet specialty drinks every single time.
- Exact OEM Match: Engineered to the precise specifications of Part # 6330030 for a seamless fit inside Crane National 623, 633, 635, 653, 673, and 677 series equipment.
- Cost-Effective Repair: Allows you to entirely rebuild the internal seals and plungers of your current Eaton valve body without buying a whole new valve block.
- Fixes Common Faults: Directly resolves issues like constant water dripping into the mixing bowls, slow cup filling, or dry powder clogs caused by poor water pressure.
- Commercial-Grade Lifespan: Crafted from premium, heat-resistant materials designed to withstand the rigorous temperature demands of commercial vending hot water tanks.
