Thermoplastic Valves Product Guide & Engineering Specifications Materials Spears® Thermoplastic Piping System Materials Benefits of Spears® Thermoplastic System Materials Unlike metal, plastics never rust, scale, or pit — they virtually last forever. Thermoplastics are abrasion resistant, chemical and corrosion resistant, nonconductive, lightweight, and operate at lower friction-loss levels than metals. Moreover, plastics are nontoxic and environmentally safe.
Thermoplastic Valves Product Guide & Engineering Specifications Materials Individual Materials Overview Thermoplastics PVC — Poly Vinyl Chloride PVC is one of the most specified thermoplastics for piping system components, including, valves, fittings, flanges, and many specialty products. PVC has excellent chemical and corrosion resistance to a broad range of fluids including water, deionized water, most mineral acids, bases, salts and paraffinic hydrocarbon solutions.
Thermoplastic Valves Product Guide & Engineering Specifications Materials FKM — Fluoroelastomer Fluoroelastomers are a special purpose fluorocarbon-based synthetic rubber categorized under the ASTM designation of “FKM”. The FKM O-ring is commonly referred to as a “Viton® O-ring”. However, “Viton® ” is only one of many FKM brand names and is a registered trademark of DuPont. Performance Elastomers L.L.C.
Thermoplastic Valves Product Guide & Engineering Specifictions Materials Temperature Pressure De-rating for PVC, CPVC & PP Thermoplastic Materials Elevated temperature fluid mediums require a de-rating of thermoplastic pipe maximum internal pressure ratings at 73°F. To determine the maximum internal pressure rating at an elevated temperature, simply multiply the pipe pressure rating at 73°F by the percentage specified for the desired temperature.
Thermoplastic Valves Product Guide & Engineering Specifictions Standards Spears® Valve Standards Standards provide greater assurance of product performance and consistency, and are available to assist design engineers in system specification. The most frequently referenced industry standards for plastic piping systems are ASTM Standard Specifications and Practices.

Thermoplastic Valves Product Guide & Engineering Specifictions General Installation Guide Ease of installation and maintenance is one of the major advantages of using thermoplastic valves. As with any product, certain procedures must be followed for successful installation, service and long life. This section specifies individual installation and maintenance service instructions for Spears® valves. All applicable instructions and procedures should be read thoroughly before starting.
Thermoplastic Valves Product Guide & Engineering Specifictions Solvent Cement Welded Joints Spears® Manufacturing Company recommends following solvent cement manufacturer’s recommendations and reading ASTM D 2855, “Standard Practice for Making Solvent-Cemented Joints with Poly Vinyl Chloride (PVC) Pipe and Fittings”. This method of joining valves and piping system components is very simple and reliable if procedures are followed correctly.
Thermoplastic Valves Product Guide & Engineering Specifictions Solvent Cement Welded Joints Step 5: Apply Primer Primer is necessary to penetrate and soften both pipe and fitting socket surfaces in order for the solvent cement to properly bond. THE MOST FREQUENT CAUSE OF JOINT FAILURES IS INADEQUATE SOLVENT PENETRATION AND SOFTENING OF BONDING SURFACES DURING THE WELDING OPERATION.
Thermoplastic Valves Product Guide & Engineering Specifictions Threaded Connections Threaded joints are used where piping system dismantling for occasional cleaning or modification is anticipated. Since threading reduces the effective wall thickness of pipe, pressure ratings of the pipe are reduced to one-half that of unthreaded pipe using solvent cement welded joints. Valves, however, have individual pressure ratings substantially different from that of pipe.
