Hello HansThank you for this information. I already checked the possibility to usecopper instead of lead. Copper is much more expensive then lead so our pricefor a version with a copperplate would cost USD 31'200. - (budgetary price).The dimension of the valve is exactly the same as for the standard 101 DN400valves (I attached the dimensional drawing to this mail) We haven't created a sketch how the plate is guided in the valve.The plate will be guided with special rollers inside the valve body.
Budgetary prices for a gate valve with a lead plate in the mechanism Series 108 DN320 Series 101 DN400 Version 1 (see attached dwg #242869) With 40mm lead plate instead of mechanism Valve is not leaktight. Pneumatic or manual actuator. Valve USD 16'000.- Version 1(see attached dwg #242869) With 50mm lead plate instead of mechanism Static seals made of Viton, metal seal optional (about USD 1'500.-) Only pneumatic actuator Valve USD 29'000.- Version 2(see attached dwg #242869) Not available for series 108 Version 2(see attached dwg #242869) With a 9mm lead plate inserted attached to the counterplate Valve leaktight according specification Valve USD 28'000.- Version 3(see attached dwg #242869) 2 valves welded together one valve with a 40mm lead plate and the other valve with a standard mechanism. Pneumatic or manual actuator. Valve complete USD 29'000.- Version 3(see attached dwg #242869) 2 valves welded together one valve with a 50mm lead plate and the other valve with a standard mechanism. Only pneumatic actuator Valve complete USD 54'000.- Pricing All prices are rough budgetary prices Mounting position: It is impossible to actuate the heavy lead plate with our standard actuator against gravity. So actuator upwards or downwards isn’t possible. Delivery Time: The delivery time for the valves is approximately 3 months.
