The HTK is available in a variety of customised designs. The custom HTK block & bleed has two seals that are placed one behind the other in the seal seat. A chamber between the seals can be used to suction off residual leakages or for barrier media.
The Hexblok Double Block and Bleed valve incorporates three valves into one, bringing the overall dimensional size down to a convenient compact package. Less leak points, less weight and small size make this the valve of choice on instrument pressure points.
