Frequently asked questions

Common questions about SPEARS from 3G Electric.

What materials are used in Spears PVC gate valves?

Spears PVC gate valves feature a PVC body and bonnet, with a solid polypropylene wedge. The stem is typically made of brass or stainless steel, depending on the model. These materials provide corrosion resistance against a range of chemicals and are suitable for water and corrosive-fluid service. The valves are rated for 200 psi CWP (cold working pressure) and are available with FIPS threaded or socket connections. For specific chemical compatibility, consult the Spears chemical resistance guide or contact 3G Electric for assistance.

What is the pressure rating for Spears slip-socket expansion joints?

The Spears slip-socket expansion joint for chemicals, such as MPN EJ21-010SR, is rated for a maximum operating pressure of 150 psi. This rating applies at the specified temperature range, typically 73°F (23°C) for thermoplastic materials. Higher temperatures may require pressure derating. The expansion joint features an EPDM bulb, which offers resistance to many corrosive fluids. For precise pressure-temperature ratings and compatibility with specific media, refer to the manufacturer's technical data or consult 3G Electric's engineering support.

Are Spears gate valves available with socket or threaded connections?

Yes, Spears non-rising stem PVC gate valves are offered with both socket (solvent weld) and FIPS (female iron pipe straight) threaded connections. For example, MPN 2012-012 has socket x socket ends, while MPN 2011-012 has FIPS x FIPS ends. Both configurations are rated for 200 psi CWP and feature a wheel operator. The choice between socket and threaded depends on the installation requirements and the piping system design. 3G Electric stocks multiple SKUs in each connection type to accommodate different project needs.

What sizes of Spears PVC gate valves does 3G Electric supply?

3G Electric supplies Spears PVC gate valves in a range of sizes, including 1/2 in, 3/4 in, 1 in, 1 1/4 in, 1 1/2 in, and larger sizes subject to availability. The part numbers follow a pattern where the suffix indicates the size; for instance, 2011-005 is 1/2 in, 2011-007 is 3/4 in, 2011-012 is 1 1/4 in, and 2011-015 is 1 1/2 in. Both FIPS threaded and socket connection styles are available in these sizes. For a complete list of stocked sizes, refer to the product catalog or contact 3G Electric directly.

Can Spears expansion joints be used in chemical piping systems?

Spears slip-socket expansion joints are specifically designed for chemical piping systems to absorb thermal expansion and contraction. The EPDM bulb provides resistance to many corrosive fluids, and the joint is rated for 150 psi. However, compatibility depends on the specific chemicals, concentrations, and temperatures involved. It is essential to verify that the EPDM material is suitable for the intended media. 3G Electric can provide material compatibility information and assist in selecting the appropriate expansion joint for a given application.

What is the maximum operating pressure for Spears PVC gate valves?

Spears PVC general purpose gate valves are rated for 200 psi CWP (cold working pressure) at 73°F (23°C). This rating applies to non-shock water and other compatible fluids. For applications involving elevated temperatures or aggressive chemicals, the pressure rating may be lower. Always consult the pressure-temperature derating curves provided by Spears. 3G Electric can supply the relevant technical documentation to ensure safe operation within the specified limits.
