Butterfly Valves

Example of a butterfly valve on a tank.

Being slim and lightweight yet robust, makes this the ideal shutoff valve for IMFO® drain.

Bolts: 316 stainless steel, titanium, C-276, Alloy 400
Body: standard PVC, CPVC and polypropylene
Size: 2˝ to 6˝
Seals: EPDM, Viton® and Viton® GF
Options: flange adapter

4 Things to Know About the Butterfly Valve

Ball Valves

Ball Valves

Complete line of high-performance Ball Valves to meet varying needs.

Body: standard PVC, CPVC and polypropylene
Connections: socketed, threaded or true union
Size: 1/2˝ to 6˝
Seals: EPDM, Viton® and Teflon®
Options: flange adapter

Flexible Hose Connections

Flexible Hose Connections

Flexible Hose Connections isolate the tank from the stresses and forces associated with pumps and piping. This connection is manufactured from ultra high molecular weight hose, which offers tremendous chemical resistance; two King nipples (barbed); and mechanically attached stainless steel bands securing the hose to the nipple. These connections are also a great solution for transitioning through secondary containment.

Connections: threaded
Nipples Option: PVC or SS
Sizes: 1˝ to 4˝

PTFE Expansion Joint

PTFE Expansion Joint

These flexible PTFE connectors and tremor barriers are designed to compensate for misalignment, absorb expansion and contraction, and isolate the vibration and shock that could damage a tank. Their low spring rate protects stress-sensitive connections. Can be installed directly to the dome of the tank to overcome piping misalignment.

  • Made of pure 100% virgin PTFE resin
  • Ethylene’s exclusive Fluorforming™ process guarantees multiple
    convolution walls of consistently uniform thickness for any size
  • Features T-Band™ root and sidewall support and protection from over-compression
  • LimitLinks™ stainless steel cables protect from over-expansion
  • Should not be attached directly to the tank wall or IMFO®. A full face flange must be installed on the tank
    first

Flange assembly materials available include:

Bolts: 316 stainless steel, titanium, C-276, Alloy 400
Flange Type: threaded or socketed
Flange Material: PVC or CPVC
Flexible Connection Minimum Specifications:
(For common size fittings and piping systems up to 6″) Contact Poly Processing for information on larger expansion joints.

• Axial Compression ≥ .67˝
• Axial Extension ≥ 0.67˝
• Lateral Deflection ≥ 0.51
• Angular Deflection ≥ 14°
• Torsional Rotation ≥ 4°

Reverse Float Level Gauges

Reverse Float Level Gauges
NOTE: These gauges are NOT intended to be used for metering purposes.

The Reverse Float Level Gauges offer a safe and reliable means of determining the chemical level in your tank and especially in the SAFE-Tank®. Available in PVC as standard.

Advantages:

  • No sidewall tank penetrations or chemical exposure
  • All joints are dry fit for easier part replacement.
  • Internal float now weighted to chemical specific gravity
  • Polypropylene rope used for indicator
  • Calibration tape can be added for tank capacity.
  • Standard or freestanding pipe supports available

Combination Internal & External Fill/Discharge Drop Pipes

Combination Internal & External Fill/Discharge Drop Pipes

Fill Line assemblies are available in PVC and CPVC with sizes ranging from 1 to 3 inches and include a true union for quick assembly. When choosing a fitting, be sure to consider if the fill will be placed on the flat of the dome; otherwise it will require a self-leveling fitting.

For dome fittings installed +/- 12 inches from the sidewall, standard pipe supports can be used. If the dome fitting is more than 12 inches from the sidewall or if the fitting size is greater than 4 inches, you must use a non-invasive internal pipe support (our “promo tank”) to support the internal piping.

Customer installation of the internal drop pipe assembly is required. Use a universal ball dome fitting for easier installation. Please note, it is recommended that one pipe support be used for every 6 feet of sidewall height to maintain alignment.

Optional fittings: ball valve, quick adapter and cap and 45°elbow as shown
