FLUIDYNE Backpressure Safety Relief or Surplus or Diaphragm Assisted Safety Relief Valve is single seated, diaphragm controlled and spring regulated valve where the pressure of the system being relieved, acting upon the diaphragm provides a sensitive control of the valve opening in accordance with the regulating spring setting. The application or ideal for installations where a direct spring loaded type is too insensitive to pressure or flow changes. The Fluidyne Backpressure Relief Valve Protects systems from overpressure and Monitors pump outputs. Fluidyne Backpressure Relief Valve is most suitable for water, air, gas, steam, oil or chemical services.

Fluidyne Boiler Full Lift Full Flow Safety Relief Valve is a high performance valve designed and developed for steam and water service. It can also be used for most other applications like gases and vapors, saturated steam, superheated steam. Fluidyne Safety Relief Valve is designed for steam service. The valves are designed as per API 520, API 526 and meets the requirements of ASME Sec VIII-Division I. Fluidyne Boiler Safety Valves are offered with IBR Certification in Form III-C. The valves have a full nozzle or half nozzle and guided at the guide of the valve body, increasing the eficiency of the valve assembly. Specially designed disc holder ensures full lift within 5% to 10% overpressure or increase of pressure above the set pressure value. Blow down of a maximum of 5% to 10% is achieved in this design. Lapping of valve seat to optical flatness ensures leak tightness at seat. Full lift of valve disc ensures that the certified flow of the safety valve is discharged. Spring made of chrome vanadium steel is precisely selected and assembled so that the valve operates precisely and a good leak tightness is achieved at high temperatures with great repeatability.

Fluidyne Deadweight Safety valve consists of a valve seat where the pressure in the boiler or pressure vessel when it exceeds the normal working pressure lifts the valve seat with its weight. The excess pressure fluid therefore escapes through the pipe to the atmosphere, until the pressure reaches its normal value. It is the simplest type of safety valve; it is suitable for stationary boilers and pressure vessels only, because it cannot withstand the jerks and vibration of mobile boilers or pressure vessels. Another disadvantage of this valve is the heavy weight required to balance the pressure. Hence, it is not suitable for high pressure boilers.

Designed for installation on pressurised vessels and storage tanks, FLUIDYNE PIPE AWAY Pressure Relief Valve is designed to protect the vessel or tank from excessive internal pressure.

In the closed position the spring-loaded pallet and diaphragm assembly is held tightly against a seal to prevent the loss of vapour to atmosphere. As the internal pressure in the tank increases, due to product filling and vapour development, the pressure in tank increases and reaching set pressure of the unit, the diaphragm will open and discharge the air, gas or steam to the atmosphere. The opening set-point is selectable from a range between +50 mbar and +1000 mbar (other settings available on request), and the valve will close when the tank returns to a safe pressure.

Several features are inherent in the valve design to ensure a smooth, positive and effective operation. The body is self-draining and drip rings prevent condensate from settling on seating surfaces. A diaphragm and seal manufactured from Teflon reduce the possibility of ice formation and sticky residues hindering the valve from opening, while the pallet assembly moves freely on guideposts. Set pressure can be adjusted by adjusting spring settings
