Gas check valve - 1 1/4 - 2", max. 27.6 bar | G200, G201 series
This valve is particularly useful for applications that require heavy-duty service, being suitable for environments of NH3 (Anhydrous Ammonia) and even LP-Gas. The way this item works is by moving the poppet right after the differential of pressure has been created. This poppet will close when the flow stops. What really impresses about this product, however, is the increase capacity, which is due to the design of the G200/G201 Series valve, which decreases flow resistance. Finally, as most internal parts are made of stainless steel, you can expect an increased resistance for this valve.
