Pilot –Operated Safety Relief Valves:

Vytal Controls Pvt Ltd pilot-operated safety Relief Valve is an autonomous valve. It does not need any auxiliary source of power to operate. The fluid under pressure in the equipment to be protected is used to actuate all operational modes.

Existing codes reflect the capabilities of both past and present Safety Relief Valve designs and allow for an accumulation above the maximum allowable working pressure before full capacity is achieved. A conventional spring loaded valve requires upto 10% over pressure to achieve full lift. This can result in the system being subjected to excessive stress during an emergency. Vytal Controls Pvt Ltd pilot operated Safety Relief Valves require no over pressure for full lift. This means the valve can be set at the desired relieving point without worry of undue system stress and possible ultimate damage.

Designed for high pressure relief pressurised spheres, vessels and pipelines. Valves are pilot operated to provide lead-free operation and full lift at set pressure. Built in accordance with ASME Boiler and Pressure Vessel Code, Section VIII, Div.I. Size range 25 mm to 200 mm inlet.

Primary advantages:

• Full lift at set pressure
• Leak-free operation upto set pressure
• Eliminates blowdown loss.
