Frequently asked questions
Common questions about SHARPE from 3G Electric.
What materials are SHARPE gate valves available in?
SHARPE gate valves are available in carbon steel, stainless steel (including CF8M, 316, and 316L), and forged steel. Wedge materials include CF8M stainless steel and 410 stainless steel. Bonnet materials match the body material, such as CF8M stainless steel, carbon steel, or forged steel. Seat materials are typically steel or metal. These material options allow selection based on media compatibility, pressure, and temperature requirements.
What pressure ratings do SHARPE valves typically have?
SHARPE valves are rated for cold working pressures (CWP) ranging from 200 psi to 1,975 psi, depending on the model and material. For example, a 2-inch 316 stainless steel non-rising stem gate valve is rated at 200 psi CWP, while a 1/2-inch forged steel rising stem gate valve is rated at 1,975 psi CWP. Flanged gate valves are available in Class 150 (285 psi CWP) and Class 300 (720 psi CWP). Always verify the specific model's pressure rating against your system's maximum operating pressure.
What types of stem configurations are offered in SHARPE gate valves?
SHARPE gate valves are available with rising stem (OS&Y) and non-rising stem configurations. Rising stem valves provide visual indication of valve position and are common in applications where stem clearance is not an issue. Non-rising stem valves are used where vertical space is limited, such as in buried or confined installations. Both configurations are offered in various sizes and pressure classes.
Are SHARPE globe valves suitable for steam service?
Yes, SHARPE globe valves are specifically designed for steam media. Models include carbon steel Z-body globe valves with FNPT connections and 316L stainless steel straight-body globe valves with FNPT connections. These valves feature metal seats and are available with non-rising or OS&Y stems. They are suitable for throttling and regulating flow in steam systems within their pressure and temperature limits.
What connection types are available for SHARPE check valves?
SHARPE swing check valves are available with FNPSM (female national pipe straight mechanical) connections, as seen in the 3/4-inch stainless steel inline swing check valve. Other SHARPE valves offer flanged connections (Class 150, Class 300), FNPT, and socket weld connections. The connection type depends on the specific model and application requirements.
Can SHARPE valves be used in petroleum and gas applications?
Yes, many SHARPE gate valves are specifically designed for the petroleum and gas industry. These include rising stem stainless steel valves with Class 300 flanges and forged steel valves with socket x FNPT connections. They are constructed with materials like CF8M stainless steel and 410 stainless steel wedges to withstand hydrocarbon service conditions. Always verify the valve's pressure rating and material compatibility with the specific media.
