The check valves feature silicon bronze bodies with FNPT x FNPT connections and NPT threads, available in pipe sizes from 3/4 in to 2 in. They are lead-free, making them suitable for potable water and other systems where lead content is regulated. The foot valves are also constructed from silicon bronze and include stainless steel strainers. They are rated for a maximum working pressure of 400 psi CWP and are available in 1 in, 1 1/2 in, and 2 in sizes. These valves are designed for pump suction lines to maintain prime and prevent backflow. Simmons products are characterized by their robust construction and compliance with relevant standards for lead-free plumbing products. The use of silicon bronze provides corrosion resistance and durability in water, oil, and gas applications. The NPT threads ensure compatibility with standard piping systems. 3G Electric supports the Simmons line by offering these products with global shipping, technical documentation, and application support. Our team can assist with selecting the appropriate valve size and type based on system requirements, such as flow rate, pressure, and connection type. We also provide access to manufacturer part numbers and specifications to facilitate procurement and integration. For maintenance and replacement, we stock common sizes and configurations to minimize downtime. Our goal is to serve as a reliable source for Simmons products, ensuring that customers receive genuine parts and responsive service. Whether you are specifying valves for a new installation or sourcing replacements for existing systems, 3G Electric can help you identify the right Simmons product for your needs.

Common Applications

  • Water treatment plants — Simmons lead-free bronze poppet check valves (e.g., MPN 505SB) prevent backflow in chemical dosing and water supply lines.
  • Irrigation systems — Simmons foot valves (e.g., MPN 456SB) maintain pump prime and prevent backflow in agricultural irrigation pump suction lines.
  • Industrial pump stations — Simmons spring-loaded foot valves with stainless steel strainers protect pumps from debris and loss of prime.
  • Plumbing systems — Simmons lead-free check valves (e.g., MPN 503SB) ensure one-way flow in potable water distribution and recirculation loops.
  • Oil and gas transfer — Simmons silicon bronze check valves handle compatible fluids in fuel transfer and lubrication systems.
  • HVAC systems — Simmons check valves (e.g., MPN 502SB) prevent reverse flow in chilled water and condenser water piping.

Frequently asked questions

Common questions about SIMMONS from 3G Electric.

What are the key features of Simmons lead-free bronze poppet check valves?

Simmons lead-free bronze poppet check valves have an inline body with FNPT x FNPT connections and NPT threads. The body is made of silicon bronze, which provides corrosion resistance. They are lead-free, making them suitable for potable water and other regulated systems. Available in pipe sizes from 3/4 in to 2 in, they prevent backflow in piping systems handling water, oil, or gas. The poppet design allows flow in one direction and seals against reverse flow. These valves are rated for a maximum working pressure of 400 psi CWP. They are commonly used in plumbing and industrial piping systems.

What is the maximum pressure rating for Simmons foot valves?

Simmons foot valves are rated for a maximum working pressure of 400 psi CWP (cold working pressure). This rating applies to the spring-loaded, inline foot valves with silicon bronze bodies and stainless steel strainers. The 400 psi CWP rating indicates the maximum pressure the valve can withstand at ambient temperature. It is important to verify that the system pressure does not exceed this rating to ensure proper function and safety. These foot valves are designed for pump suction lines to maintain prime and prevent backflow. They are available in 1 in, 1 1/2 in, and 2 in sizes with FNPT connections.

Are Simmons check valves suitable for potable water applications?

Yes, Simmons lead-free bronze poppet check valves are suitable for potable water applications. They are constructed with lead-free silicon bronze, which complies with regulations limiting lead content in plumbing products. The lead-free construction ensures that the valves do not introduce lead into the water supply. They are commonly used in potable water systems, as well as in industrial piping systems handling water, oil, or gas. The NPT threads and FNPT connections allow for standard installation. Always confirm local codes and standards for specific potable water requirements.

What sizes of Simmons foot valves does 3G Electric supply?

3G Electric supplies Simmons foot valves in 1 in, 1 1/2 in, and 2 in pipe sizes. These are spring-loaded, inline foot valves with silicon bronze bodies and stainless steel strainers. They feature female NPT connections and are rated for 400 psi CWP. The 1 in size is suitable for smaller pump systems, while the 1 1/2 in and 2 in sizes are used in larger flow applications. All sizes are designed for pump suction lines to maintain prime and prevent backflow. 3G Electric can provide availability and lead times for these sizes upon request.

How do I select the right Simmons check valve for my application?

To select the right Simmons check valve, consider the pipe size, connection type, and system pressure. Simmons poppet check valves are available in 3/4 in, 1 in, 1 1/4 in, 1 1/2 in, and 2 in sizes with FNPT x FNPT connections. Ensure the valve's maximum working pressure (400 psi CWP) exceeds your system pressure. The lead-free silicon bronze construction is suitable for water, oil, and gas. For pump suction lines, consider Simmons foot valves instead. 3G Electric can assist with selection based on your flow rate, pressure, and fluid compatibility requirements. Provide your system specifications for a recommendation.

What is the difference between a Simmons check valve and a Simmons foot valve?

Simmons check valves are inline poppet valves designed to prevent backflow in piping systems. They are installed within the piping and allow flow in one direction. Simmons foot valves are also inline but are specifically designed for pump suction lines. They include a stainless steel strainer to prevent debris from entering the pump and are spring-loaded to maintain prime. Both use silicon bronze bodies and are lead-free. Check valves are available in sizes from 3/4 in to 2 in, while foot valves come in 1 in, 1 1/2 in, and 2 in. Both are rated for 400 psi CWP.
