Valves from Erdmann Corporation

Valves are mechanical or electromechanical components used to control the movement of fluids and fluid-like substances through piping and tubing systems. They generally rely on a mechanical barrier component to allow or stop the flow of material. Beyond this shared characteristic, valves may vary significantly in regard to design, construction, and application. 

At Erdmann Corporation, we’ve supplied industrial valves to customers and contractors for over 80 years. The valves we offer are:

  • Ball valves
  • Butterfly valves
  • Gate valves
  • Diaphragm valves
  • Plug valves
  • Globe valves
  • Check valves

Below we provide a more comprehensive overview of our product offerings. Check out our full catalog of valves to browse for your next valve or examine our line card to see the brands that we carry.


Ball Valves


Ball valves are quarter-turn rotary valves that feature a ball-shaped mechanical barrier with a straight bore between two cup-shaped valve seats. When the valve is open, material flows through the ball. When the valve is closed, the bore is not aligned with the seat openings and material cannot pass through it. 

Our ball valves come in several designs, such as split-body and unibody, regular, full, V, and multiple port, in-line repairable, soft seated or metal seated, and gear-operated. They are available in many construction materials, including:

  • Alloy 20
  • Bronze
  • Carbon steel
  • Ductile iron
  • Hastelloy
  • Lined
  • PVC
  • Sanitary
  • Stainless steel
  • Titanium

Butterfly Valves

Tufline Fully Lined Butterfly Valve

Butterfly valves are quarter-turn valves that feature a circular, disc-shaped mechanical barrier and single valve seat. When the disc is parallel to the direction of flow, material can move through the valve. When the disc is perpendicular to the direction of flow, material cannot move through the valve. 

Our butterfly valves are available in the following models: 


  • Resilient seated: general-duty valves designed for use in on/off and throttling applications up to 200 psi (in 2 to 12-inch sizes) and up to 150 psi (in 14 to 48-inch sizes)
  • High-performance: valves designed for long-term use even in harsh operating conditions
  • Triple offset: valves designed to reduce wear stemming from sealing surface contact while maintaining a strong seal in high cycle operations
  • Jacketed: high-performance valves designed for use in rail tank car applications
  • Steam traced and jacketed: valves designed to prevent the solidification of material
  • Fully lined: valves designed to withstand use with corrosive materials

Gate Valves


Gate valves feature a plate-shaped barrier that moves up and down to start and stop flow, respectively. They are generally used for on-off applications.

Our gate valves are available in wedge, knife, slide, and AWWA/UL/FM compliant variations. They are available in several construction materials, including:

  • Alloy
  • Bronze
  • Carbon steel
  • Chrome
  • Ductile iron
  • PVC
  • Stainless steel

Diaphragm Valves

Saunders Industrial Diapragm Valves

Diaphragm valves rely on flexible membranes to stop flow and separate the actuating mechanism from the process material. This latter quality makes them ideal for use in sanitary applications, such as cosmetic, food, and pharmaceutical product manufacturing. 

We offer the following diaphragm valves: 


  • ITT and Saunders diaphragm valves: available in sizes ranging from ¼ to 14 inches and accommodates pressures from vacuum to 230 psi in general industrial operations
  • Weir diaphragm valves: provides superior performance in sanitary operations

Plug Valves

Tufline Jacketed Plug Valve

Plug valves operate similarly to ball valves, except they employ a cylindrical—rather than spherical—mechanical barrier to control flow. Our plug valves are available with several design options, including sleeved, jacketed, or fully lined bodies and rectangular, full, or multiple ports. 

Examine our full offering of plug valves in our online catalog.


Globe Valves

Globe valves are linear motion valves designed to regulate flow through a system. They feature a rising stem design that lowers or raises the mechanical barrier to stop and start flow as needed. Typical applications include flow control in chemical feed systems, cooling water systems, fuel oil systems, heater and boiler systems, and turbine systems. 


Check Valves

Check Valves

Check valves—also known as one-way or non-return valves—allow for fluid flow in a single direction. In the event fluid flow reverses direction during operations, they are designed to close automatically. This characteristic prevents backflow, which can cause damage to system components and, in extreme cases, system failure. Some examples of typical applications include centrifugal pump systems and HVAC systems. 

We offer the following types of check valves: swing, piston, silent, and dual disc wafer check valves. Similar to our gate valves they are available in a variety of construction materials.
