Safety Valve with Radiator, API 526, A216 WCB, DN100, PN16

Key Specifications / Features

The Full Open Spring Safety Valve is designed per API 526, featuring a durable ASTM A216 WCB carbon steel body for high-temperature applications. Sized at DN100 (4 inches) with a PN16 (Class 150 LB) pressure rating, it ensures reliable overpressure protection. Equipped with a radiator for enhanced heat dissipation, this valve is ideal for steam, gas, and high-temperature fluid systems, providing precise and efficient pressure relief.

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