FEATURES & BENEFITS

DISCHARGE CAPABILITIES

The NABIC 500 is designed primarily for use on unvented hot water heating systems, where a high capacity, emergency steam relief capability is required. All wetted parts are manufactured from dezincification resistance materials. Designed and tested to BS EN ISO 4126 -1.

WRAS approved DN15 to DN25 - 1 bar and above; DN32 to DN65 - 0.4 bar and above;

Size Range: DN15 - DN65 Resilient PTFE seating design with high degree of seat tightness Easy inspection and cleaning High discharge capacity Diaphragm protected parts Available with Viton seat design Padlock available (complies with M&E3) Pressure setting locked and sealed Drain plug fitted on DN32 and above

• • • • • • •

The discharge capacity of a safety valve must be equal to or greater than the output of the boiler or system it is protecting.

To ensure that the correct method of sizing is used, reference should be made to the relevant BS specification for the design of the boiler or system. Fig 500 capacities are tabulated below to assist selection.

FEATURES & BENEFITS

DISCHARGE CAPABILITIES • •

Size Range: DN15 - DN65 Resilient PTFE seating design with high degree of seat tightness Pressure tight on discharge side Suitable for liquids and inert gases Available with Viton seat design Pressure setting locked and sealed Drain plug fitted on DN32 and above WRAS approved

• • • • • •

The discharge capacity of a safety valve must be equal to or greater than the output of the boiler or system it is protecting.

To ensure that the correct method of sizing is used, reference should be made to the relevant BS specification for the design of the boiler or system. Fig 500L capacities are tabulated below to assist selection.

The NABIC Fig 500L is designed primarily for use where high tightness is required on the discharge side. A sealed spring cover prevents the possibility of back pressure leakage through the top of the valve. The lift is progressively proportional to flow. All wetted parts are manufactured from dezincification resistance materials.

Designed and tested to BS EN ISO 4126 -1.

FEATURES & BENEFITS

TEMPERATURE RATING

The NABIC Fig 500T provides protection against excess temperature as well as pressure protection. It automatically discharges hot water to prevent a predetermined set pressure and/or temperature being exceeded. Each of the lift mechanisms is independent of each other. Designed and tested to BS EN 4126, BS 6283 (when 50% of BS EN ISO 4126 -1 ratings at 1 bar or temperature ratings are used). WRAS approved (1 bar and above). Valve is suitable for PED2014/68/EU cat 1 use only.

PRESSURE RATINGS & TEMPERATURE RANGE

PART NAME & MATERIALS

The discharge capacity of the safety valve must be equal to or greater than the output of the boiler or system it is protecting.

Two methods of sizing are employed for combined pressure and temperature relief valves; one, based on the pressure element of the valve, the other based on the temperature element. To ensure that the correct method is used, reference should be made to the relevant BS specification to the design of the boiler or system. If in doubt, choose the method which produces the lower rating.

The capacity of an anti-vacuum valve should be equal to or greater than the rate of the vacuum formation in the vessel being protected. To assist selection, reference should be made to BS 853 cl 10.3 or to the capacities of the Fig 568 tabulated below: AIR std. litres/sec

INSTALLATION Fig 568 Anti-Vacuum valves are used to protect drying cylinders, storage cylinders, calorifiers and tankers from collapse due to internal vacuum. They are also used on the steam systems, to assist condensate drainage and to prevent suction of contents from vats. Vacuum Valves are normally fitted vertically, at the top of the vessel or pipeline being protected, horizontal revolving cylinders however should have a Fig 568 fitted at each end, diametrically opposite one another. The operation of valves in service should be checked every twelve months.
