GENERAL

1. The poppet is loaded by a spring in a normally open position as long as the system is balanced.2. If the system becomes unbalanced and the downstream pressure drops, the poppet moves towardsthesealingareaandpreventsfree,uncontrolledexcessflowfromtheline.3. If the downstream pressure increases, the ventilation outlet ("bleeding") enables the system to balance the pressures and (with the help of the spring) reset the system. In this situation, the poppet reverts back to Normally Open.

Excellent for Automatic Safety Shutoff in a wide range of areas:

n Fuel systems n Toxic Media Systems n Gas Systems n Valued Media Systems

n Hydraulic & Pneumatic Systems.

SpringResets the system backto the normally open position whenthe downstream pressure equalizesthe upstream pressure.

Vent "Bleeding"Enables "information transfer" between the two sides of the valve, and automatically resets the system.

Metal SealingImproves stability and repeatability.Does not need maintenance.

Poppet- Produced from stainless steel.-Enableshighflowrates.- Improves reliability and performance.

SETTING AND RESEALING PRESSURE

n Upstream set pressure is the first indicator of flow process. Every pressure relief after the first indication is repeatable within a deviation of 5% at room temperature.

n Blocked upstream set pressure is the first indicator of a stopped flow process and is always lower than the set pressure.n Calculation of set pressure valve design demands

back pressure consideration as the system back pressure increases the set pressure. To balance the system, the back pressure must be multiplied by 0.8 and the result shall be subtracted from the required set pressure.

n Lubricant free cleaned valves have higher reseal pressure

APPLICATIONSH-900 relief valves gradually open when pressure increases. As such, they are not certified to ASME due to not having capacity rating at a given pressure rise (accumulation).

OPERATIONH-900 relief valves open when the system pressure gets to the set pressure and close when the system pressure drops below the set pressure.

Warning

n Valves that were not actuated for some time may contain pressure higher than the set pressure.

n System designer and users shall determine what system applications require using relief valves to meet specific safety codes and which valves conform to such codes.

H-900HP, Rev.10, January 2015

APPLICATIONSH-900HP relief valves gradually open when pressure increases. As such, they are not certified to ASmE due to not having capacity rating at a given pressure rise (accumulation).

OPERATIONH-900HP relief valves open when system pressure gets to the set pressure and close when system pressure drops below the set pressure.

Warning

n Valves that were not actuated for some time may contain pressure higher than the set pressure.

n System designer and users shall determine what system applications require using relief valves for meeting specific safety codes and which valves conform to such codes.
