The Flomatic 2030 1" 901 insert plastic check valve is a compact, non-corrosive valve designed for use with water meters and other small-diameter piping systems where protection against backflow and contamination is required. This model features an acetal check valve body and guide, an insert-style connection, a Nitrile (Buna-N) seal, and a stainless-steel spring. It is rated for a maximum working pressure of 150 psi and a maximum temperature of 180°F (80°C).

Specifications:

Max Pressure: 150 psi

Max Temperature: 180°F (80°C)

Body: Acetal

Guide: Acetal

Seal: Nitrile (Buna-N)

Spring: Stainless steel

Connection: 1" insert connection

Weight: 0.033 lbs

Operation: The internal spring-loaded poppet closes quickly at low reverse flow to help prevent backflow and loss of line integrity, while the insert connection provides a compact, low-profile installation directly in the meter or fitting body. When forward flow resumes, the spring and differential pressure reopen the valve to restore flow through the system.

Construction: The 901 series combines a non-corrosive acetal body and guide with a stainless-steel spring and resilient Nitrile (Buna-N) seal to deliver reliable performance in cold and hot potable water applications. The streamlined flow path and insert-style geometry support good hydraulic performance in tight meter layouts and small service connections.

Applications: Water meter installations, small service lines, and general light-duty water systems requiring a compact insert check valve to help protect against contamination and backflow.
