Industrial Check Valve, Conical Seat, Female NPT x Female NPT - Configurable dimensions

Dixon's Series 61 and 62 check valves represent a step forward compared to standard rubber seal valves. Their Reinforced PTFE Cone Seat design allows them to operate over a much wider temperature range (-29°C to 178°C), making them suitable not only for water and oil, but also for Saturated Steam (up to 125 PSI) and aggressive chemical fluids.

This product is offered in two construction variants to suit your budget and needs:

1. Series 61 (Brass Body): The ideal option for water, air, and non-corrosive oil lines.

2. Series 62 (316 Stainless Steel Body): The mandatory choice for marine environments, food industry, chemicals, or when maximum hygiene and durability are required.

Both versions feature an internal spring that ensures quick and tight seating with a minimum opening pressure of only 0.5 PSI, functioning effectively in any installation position (vertical or horizontal).

Key Technical Features:

• Reinforced PTFE Seal: Unlike rubber (NBR) which burns with steam, PTFE withstands high temperatures and offers excellent chemical resistance.

• Direct Flow Design: Internal profile designed to minimize turbulence and fluid velocity variations.

• Dual Pressure Rating:

  • 400 PSI WOG: For Water, Oil, and Gas at ambient temperature.

  • 125 PSI Steam: Suitable for saturated steam lines.

• Precision Engineering: Does not require radial alignment for proper sealing.
