✅Full Lift Action: Designed as a Full Lift type (opening height ≥ 1/4 throat diameter), allowing for a massive discharge capacity to quickly relieve excess pressure, making it superior to Low Lift Safety Valves for large volume vessels.

✅Manual Testing Lever: Equipped with a Packed Lifting Lever that allows operators to manually open the valve to verify freedom of movement and clear debris from the seat, meeting boiler safety code requirements.

✅Open Bonnet Design: The open bonnet construction exposes the spring to the atmosphere, dissipating heat effectively and preventing spring relaxation in high-temperature Steam applications (up to 450°C).

✅Precise Blowdown Control: Features adjustable blowdown rings that allow technicians to fine-tune the Reseating Pressure (difference between opening and closing pressure), preventing valve chatter and reducing product loss.

✅Durable Sealing Surface: The disc and seat are hard-faced with Stellite (CoCr alloy) or ground stainless steel, providing exceptional resistance to steam erosion and ensuring a tight seal after repeated popping cycles.
