ASME Code Flanged End Elevated Platform Stainless Steel Ball Valve

Engineered for demanding industrial applications, our ASME Code Flanged End Elevated Platform Stainless Steel Ball Valve represents the pinnacle of durability, precision, and compliance. Designed for seamless integration into high-pressure and corrosive fluid systems, this valve features a robust elevated (extended) platform that provides critical clearance for actuators and manual gear operators, ensuring safe and ergonomic operation in confined spaces. Its construction strictly adheres to ASME B16.34 and other relevant standards, guaranteeing dimensional interchangeability, pressure integrity, and global acceptance in oil & gas, chemical processing, power generation, and marine industries. The flanged ends, conforming to ASME B16.5, facilitate secure and leak-proof bolting to piping systems, significantly reducing installation time and maintenance concerns. For applications requiring superior resistance to aggressive media, we offer specialized variants such as the High Platform Corrosion-Resistant Steel Ball Valve with ASME Standard Flange. Furthermore, our comprehensive range includes the ASME Standard Flange Connection Industrial Stainless Steel Ball Valve, designed for heavy-duty industrial service where reliability under extreme conditions is non-negotiable.


The ASME Code Flanged End Elevated Platform Stainless Steel Ball Valve is meticulously manufactured from high-grade stainless steel, typically ASTM A351 CF8M (316 stainless) or CF8 (304 stainless), providing exceptional resistance to corrosion, pitting, and oxidation across a wide temperature range. The full-port design ensures minimal pressure drop and allows for efficient pigging or cleaning of the pipeline. Critical components like the ball and seats are precision-machined and often coated with advanced materials like PTFE (Teflon) or reinforced polymers for enhanced sealing performance, low operating torque, and extended service life. The elevated platform (also known as an extended stem) is a key safety feature, protecting the stem threads from direct exposure to process fluids and external contaminants while allowing for easy insulation of the valve body. A multi-step stuffing box with high-quality graphite or PTFE packing ensures a superior stem seal, preventing fugitive emissions. This valve is designed for bi-directional flow and bubble-tight shut-off, performing reliably in both on/off and moderate throttling services. Fire-safe design per API 607/ISO 10497 standards is available as an option, providing an added layer of safety in hazardous environments. Every valve undergoes rigorous pressure testing, including shell test, seat test, and high-pressure gas test, to validate its performance before shipment.

  • The difference between double eccentric butterfly valve and triple eccentric butterfly valve

    First, think about the most common faucet in your home, or the old-fashioned iron disc valve you have seen. The piece (disc) of that switch is threaded through a shaft (valve stem) in the center. When it's opened or closed, that disc rubs against the sealing ring, just like rubbing an eraser against a table. Over time, it will definitely leak.

  • The way the gate valve moves

    When the gate valve is closed, the sealing surface can only rely on the medium pressure to seal, that is, only rely on the medium pressure to press the sealing surface of the ram to the valve seat on the other side to ensure the sealing of the sealing surface, which is self-sealing.

  • How Electric Butterfly Valve Operate and Their Uses

    Electric butterfly valves​ are essential for controlling the flow in industrial systems. These valves operate using an electric motor to rotate a disc inside the valve, which adjusts the amount of liquid or gas that can pass through.
