PRAHER PLASTICS 2" Single-Union Ball Valve SKT x SKT Model 200-010 — 2" Grade 1 PVC, 150 PSI

Praher's 2" single-union ball valve (SKT x SKT, model 200-010) is a durable Grade 1 PVC union valve designed for solvent-weld installation, offering reliable 150 PSI performance and a secure pinned retainer-ring for safe disassembly.

This compact union ball valve is built for systems that require solvent-socket connections and occasional line separation without sacrificing pressure capacity. Constructed from Grade 1 PVC with EPDM/Nitrile O-rings and polyethylene ball seats, the 200-010 balances chemical resistance, low friction, and long life in irrigation, pool, water treatment, and light industrial piping. Its retainer-ring is locked with two pins to prevent unintentional movement while still allowing intentional disassembly when needed.

How does the SKT x SKT (socket) configuration affect installation?

The socket ends are intended for solvent-weld (cement) joints, which create a smooth, continuous bore and eliminate threaded leak paths. That makes the valve faster to install for technicians who prefer welding PVC systems and maintains the Schedule 80 bore alignment for predictable flow. No threads means fewer sealing materials and a cleaner external appearance.

• Socket (SKT) ends for solvent-cement joining
• Schedule 80 bore for consistent internal diameter
• Eliminates need for thread tape or mechanical unions

What materials are used and why do they matter for longevity?

The body is Grade 1 PVC, chosen for strength and chemical resistance; EPDM or Nitrile O-rings are used depending on application needs; and polyethylene seats reduce wear against the ball. Together these materials minimize leaks, resist common pool and irrigation chemicals, and lower friction for smoother operation over time. The combination supports a 150 PSI working pressure rating when installed correctly.

• Grade 1 PVC body for structural durability
• EPDM/Nitrile O-rings for flexible sealing options
• Polyethylene ball seats for low friction and wear resistance

How secure is the valve when lines must be disconnected?

The 200-010 is engineered so the retainer-ring cannot shift during normal operations: two locking pins secure it in place. This prevents the ball or ring from moving accidentally when disconnecting lines, reducing the risk of component loss or damage. When intentional disassembly is required, the locked retainer-ring can be removed in a controlled manner by qualified personnel.

• Retainer-ring locked with two body-mounted pins
• Design reduces accidental ball or ring movement during separation
• Enables safe, planned line disconnection when needed

Where is this valve most commonly used and what are typical limitations?

This valve is frequently used in irrigation, swimming pool systems, aquaculture, water treatment, and many light industrial PVC piping applications that use solvent-weld connections. It's not intended for threaded systems or high-temperature steam service; compatibility with specific chemicals should be checked against material data. Always follow local codes and installation best practices for pressure and temperature limits.

• Common: irrigation, pools, water-treatment, aquaculture
• Limitations: not for threaded fittings or high-temperature steam
• Verify chemical compatibility for aggressive fluids

Who is this for: The Praher 2" single union ball valve 200-010 is designed for contractors, system integrators, and maintenance teams who prefer solvent-socket PVC systems and need a robust, serviceable valve rated to 150 PSI. Choose this model when you want a Schedule 80 bore, reliable O-ring materials (EPDM or Nitrile), and a pinned retainer-ring to reduce risk during planned disassembly. If your project uses threaded connections or requires exotic material compatibility, consider alternate fittings or consult product specifications before ordering.
