The Renewable Valve and Seat is made of
Hopkinson’s “ Platnam ” Metal
which is suitable for superheated steam and bad waters.

There are many valves with renewable valve and seat upon the market, but under modern
conditions and high pressures do not last any length of time owing to the deterioration which
takes place on the valve and seat, and consequently the renewing of the parts is a frequent
occurrence. We have tried our “Platnam” Meta’l under severe conditions, and, have every
confidence in recommending it to work under high temperatures. The “MAC” valve has
been designed to adopt this metal for the renewable valve and seat.
