840 Series Butterfly Valve - Cast Iron Body, Wafer Style
Product Overview
System shutdowns during peak irrigation season are a nightmare for any contractor, leading to browned turf, crop loss, and costly emergency service calls. When a main header valve fails or leaks under pressure, your entire project comes to a standstill while labor costs continue to climb. With summer heat windows tightening and supply chain volatility causing long lead times on heavy iron components, waiting until a valve fails is a risk to your reputation. Securing your inventory of reliable butterfly valves now ensures you avoid back-order delays and keep your crews moving during the high-demand months. Planning ahead provides the relief of knowing your installations will pass inspection and operate without interruption when your clients need water most.
The Soval 840 Series Butterfly Valve offers a significant technical advantage over standard gate valves through its compact wafer design and superior flow control. The streamlined profile reduces the physical footprint of your manifold, saving space in tight vaults and reducing the overall weight of the piping assembly. This translates to faster installation times and less physical strain on your crew during assembly. By choosing a high-grade cast iron body with a resilient seat, you minimize long term maintenance costs and prevent the common seizing issues associated with lower-quality alternatives. Maintaining a stock of these valves gives you a competitive edge by allowing for rapid deployment and professional, high-performance results on every site.

Key Features
- Cast iron body construction provides exceptional structural integrity and resistance to mechanical stress in demanding environments.
- The wafer style design allows for easy installation between existing flanges, reducing the complexity of retrofitting older systems.
- Phenolic backed EPDM seats ensure a bubble tight seal and prevent seat deformation under high pressure cycles.
- Extended neck design provides ample clearance for piping insulation and allows for easy access to the actuator or handle.
- The stainless steel stem utilizes a heavy duty bushing to ensure smooth operation and consistent torque throughout the life of the valve.
- Corrosion resistant epoxy coating protects the exterior body from soil moisture and harsh chemicals found in fertigation setups.
Common Applications
- Commercial landscape irrigation
- Agricultural and crop irrigation
- Sports turf and golf course maintenance
- Municipal parks and public spaces
- Greenhouse and nursery operations
- Potable water supply systems
Installation Notes
Install the 840 Series Butterfly Valve using standard ANSI 125 or 150 weld neck or slip on flanges. Ensure the disc is in the partially open position during installation to prevent damage to the resilient seat during flange bolt tightening. No gaskets are required for the wafer style as the seat face provides the necessary sealing surface against the flanges. Always follow local plumbing codes and manufacturer torque sequences to ensure a leak free connection and optimal operation of the lever handle.
