its a device use for measuring the salinity of boiler water.
it is generally fitted in water drums .its is provided to prevent the flashing off of boiler water under high pressure condition.
Raise the pressure in the boiler until the valve relieves and note the pressure at which it does so.
Stop Boiler Valve (or Crown Valve) is installed on an outlet line of a boiler. It's purpose is isolation of a boiler from a downstream steam line. Its position may be either open or close, it cannot be used for throttling of steam.
The relief valve should be at least as large (in BTU/hr capacity) as the input of the boiler. A 3.5 million input boiler would need then a relief valve to handle at a minimum 3.5 million BTU/hr.
They are just about the same
The lifting pressure is set by turning the adjusting nut on top of the valve.

A salinometer measures the amount of salt in something.

Not for the faint of heart! For a Combi/Evaporation boiler: Switch off the boiler. Take a reading of the boiler water pressure gauge. Shut off the radiator's thermostat valve(if fitted)/supply valve and return valves, connect a hose to the drain and put the other end into a large container below the level of the bottom of the radiator. Open the draincock first and then the air bleed valve and let the radiator drain. Close the draincock. When refilling the radiator put the anti-corrosion treatment in first then open the thermostat valve and return valve as wide as possible. when the air is expelled, close the air bleed screw. Using the fill loop restore boiler pressure. Put all thermostat valves(if fitted) to max and fire up the boiler. After the boiler has run for 10 minutes, switch off, or so go to the highest radiator and bleed out the air. WARNING: the water/steam will be very hot and likely to spit. Use a cloth as a barrier and to mop up any spills. Recheck the boiler pressure and top up as necessary.
is it a diverter valve or immersion heater then? only need a simple answer haha
Its a Boiler that is fitted with two or more heating sources. Say Gas and Oil Fired
The feed check valve of a boiler is on the line coming out of the boiler it is usually to prevent the water from going back in to the boiler its coming out of so it would build up excessive amounts of pressure which will cause the t&p valve to blow temperature and pressure
Safety valve simmering how can setting

Your boiler pressure relief valve may be leaking due to high pressure in the system, a faulty valve, or a buildup of sediment or debris. It is important to address this issue promptly to prevent further damage to your boiler.
