ASTM A216 WCB Safety Valve, API 526, DN50, PN64, Full Lift

Key Specifications / Features

The ASTM A216 WCB Safety Valve, manufactured in compliance with API 526 standards, features a carbon steel body for durability and strength. With a DN50 (2-inch) size, Class 400 LB pressure rating, and PN64, it is designed for full lift and spring-loaded operation, providing reliable pressure relief in critical systems. The flanged ends ensure secure and easy installation.

The Spring Full Lift Safety Valve is designed for systems with relatively simple discharge requirements. It can be used in systems where the discharge pressure is atmospheric, constant, or may increase up to a maximum of 10% above the set pressure. In cases with constant back pressure, the valve should be set to the differential pressure. The valve disc sealing surface is available in two types: flat and conical. The discharge area is calculated based on the cylindrical or conical surface formed between the valve disc and seat. This valve is ideal for applications with small discharge capacities, high back pressure, and stable system pressure.
