WEBSTONE

Webstone is a manufacturer of valves and fittings for hydronic heating, plumbing, and industrial piping systems. The company was founded in 1954 in the United States and has since built a catalog centered on brass and bronze valves, purge and purge-and-balance valves, ball valves, boiler installation kits, and related components. Webstone products are commonly specified in hydronic heating loops, boiler rooms, and water distribution systems where isolation, purging, and flow balancing are required. The product families include manual two-way ball valves, purge valves, boiler drain valves, and installation kits that combine multiple components into a single assembly. Many Webstone valves are constructed with brass bodies and full-port ball designs to minimize pressure drop. Connection options include female iron pipe (FIP), sweat (solder), and flange ends, with handle styles such as lever and tee. Pressure ratings for the brass ball valves shown here reach 600 psi cold working pressure (CWP), and sizes range from 3/4 inch to 2 inches in the listed models. These valves are used for on/off service in water, oil, and gas applications, subject to the specific rating and compatibility of the selected model. 3G Electric supplies Webstone products globally to plant engineers, maintenance managers, and procurement specialists. The catalog includes individual valves and kits, with specifications such as body material, port type, connection type, handle style, and pressure rating listed for each item. 3G Electric supports the line by providing product data, cross-referencing manufacturer part numbers, and fulfilling orders for single units or bulk quantities. For technical buyers, the key selection criteria are connection size and type, port configuration (full or standard), pressure and temperature ratings, and media compatibility. Webstone’s product range addresses common hydronic and plumbing isolation and purge points, and 3G Electric maintains inventory and logistics to ship these components to industrial and commercial sites worldwide.

Common Applications

  • Hydronic heating systems — Webstone brass ball valves with sweat x flange connections for isolation of boiler loops and terminal units.
  • Boiler room piping — Webstone FIP x flange ball valves rated to 600 psi CWP for on/off control of water and steam lines.
  • Plumbing riser isolation — Webstone full port ball valves with lever handles for minimal pressure drop in domestic water distribution.
  • Industrial process piping — Webstone tee handle ball valves for manual shutoff in oil and gas lines where accidental actuation must be avoided.
  • Purge and balance applications — Webstone purge valves and boiler installation kits for air removal and flow balancing in hydronic circuits.
  • Retrofit and repair — Webstone ball valves with flange outlets for direct replacement on existing flanged pipe ends without adapters.

Frequently asked questions

Common questions about WEBSTONE from 3G Electric.

What is the maximum pressure rating for Webstone brass ball valves?

Many Webstone brass ball valves in the 3G Electric catalog are rated to 600 psi cold working pressure (CWP). This rating applies to the valve body and seats under static conditions at ambient temperature. Actual working pressure may be lower at elevated temperatures, depending on the seat and seal materials. Always verify the specific model’s pressure-temperature rating before installation. The 600 psi CWP rating is common across the FIP x flange and sweat x flange ball valve models listed, such as MPN 40407HV and 41404HV.

What connection types are available on Webstone ball valves?

Webstone ball valves are available with several connection combinations. The models shown here include FIP (female iron pipe) x flange, sweat (solder) x flange, and straight patterns. For example, MPN 50407HV has sweat x flange connections, while MPN 41405HV has FIP x flange. Flange connections allow direct mounting to flanged pipe ends, and sweat connections are soldered to copper tubing. FIP connections thread onto male pipe threads. Selection depends on the existing piping system and the required joint method.

What is the difference between a full port and a standard port Webstone ball valve?

A full port ball valve has a bore size equal to the nominal pipe size, which minimizes pressure drop and allows for pigging or passage of line-cleaning devices. A standard port valve has a smaller bore, which reduces cost and size but increases pressure drop. Webstone offers both configurations. The models listed here, such as MPN 40403 and 51405HV, are full port. Full port is often specified where flow capacity is critical or where pressure loss must be kept low.

Are Webstone ball valves suitable for gas service?

Webstone brass ball valves are used for on/off service in water, oil, and gas applications, as indicated in the product descriptions. However, suitability for a specific gas depends on the valve materials, seals, and any applicable codes. For natural gas or propane, verify that the valve is rated for the specific gas and that local codes permit its use. The valves listed here are not specifically marked for gas service in the provided data, so always confirm compatibility with the manufacturer and applicable regulations before installation.

What handle options are available for Webstone ball valves?

Webstone ball valves come with different handle styles to suit the installation. The models in the 3G Electric catalog include lever handles and tee handles. Lever handles provide a visual indication of the valve position (open or closed) and are common in general service. Tee handles are often used where a lever might be accidentally bumped or where a lower profile is needed. Both are manual operators for two-way flow control. The handle style is specified in the manufacturer part number and product description.

How do I select the right Webstone ball valve for my application?

Selection depends on several factors: connection size and type (FIP, sweat, flange), port configuration (full or standard), pressure and temperature ratings, and media compatibility. Start by determining the pipe size and connection method. Then confirm the required pressure rating—many Webstone brass ball valves are rated to 600 psi CWP. Choose full port if minimal pressure drop is needed. Verify that the valve materials are compatible with the media (water, oil, or gas). Finally, select the handle style (lever or tee) based on the installation environment. 3G Electric can provide spec sheets and cross-reference part numbers to assist.
