The Hayward SP0729 Econoline 2-way ball valve is a corrosion-resistant 1-1/2" flow control valve with a dial handle and union end for fast, leak-minimized servicing.

If you manage pool, spa, or light industrial water lines and need a compact valve that balances dependable sealing with easy maintenance, the SP0729 offers a practical solution. Built from non-corrosive materials and fitted with Teflon seats, this 1-1/2" valve was engineered to deliver efficient flow at pressures up to 50 psi while keeping disassembly straightforward through its union connector. Its clear dial handle gives a visual read on the valve position so you can adjust flow without guesswork.

How does the SP0729 help control flow and pressure?

The SP0729 is a two-way ball valve sized for 1-1/2" lines that provides smooth regulation of water movement. The ball mechanism creates an unobstructed flow path when open and a reliable shutoff when closed, while the pressure rating supports typical residential and light commercial pool systems.

• 1-1/2" MIP inlet/outlet for common pool plumbing runs
• Rated up to 50 psi for standard circulation and return lines
• Ball design minimizes flow restriction in the open position
• Dial handle enables fine adjustment of flow

What makes this valve easy to service and install?

The valve’s union end connector aligns the internal ball and allows quick separation of piping without cutting or complex tools. This simplifies routine maintenance, replacements, or winterization tasks and reduces downtime for pool equipment.

• Union end provides tool-free disassembly for inspections
• Adapter options (1-1/2" by 1-1/2" hose adapter included) for flexible hookups
• Compact footprint fits tight valveboxes and equipment pads
• Corrosion-resistant construction reduces long-term upkeep

How reliable is the sealing and handling in long-term use?

The SP0729 uses Teflon seating material that resists wear and provides a consistent seal across multiple open/close cycles. Combined with the non-corrosive body and clear dial indicator, the result is a valve that maintains performance with less frequent adjustment or part replacement.

• Teflon seats for low-friction, dependable sealing
• Dial handle gives immediate visual confirmation of valve position
• Non-corrosive components reduce the chance of leaks from material degradation

Which connections and accessories come with the SP0729?

The package includes a 1-1/2" MIP pipe connection and a 1-1/2" by 1-1/2" hose adapter to match common pool plumbing and flexible hose setups. These options let you adapt the valve into existing systems without custom fittings.

• 1-1/2" male iron pipe (MIP) threaded connection
• 1-1/2" to 1-1/2" hose adapter for flexible hose attachments
• Union end for straightforward alignment and removal
