Axial Check Valve Range

The axial design of the ZB range results in a streamlined flow path around the disc and high pressure recovery, minimising pressure drop across and maximising flow through the valve.

The axial design of the ZD range has the same streamlined flow path around the disc and high pressure recovery as the ZB but with a long face to face dimension in accordance to API 6D

The NB employs the worldwide proven ring disc/radial guide design. With its friction free guiding and the aerodynamic flowpath through its two ring shaped flow ports, the NB is “best in class” for speed of response and flow capacity.

The NK is the compact model of ring disc/radial guide design. With its short face-to-face and reduced weight, the compact NK is a lower cost solution to the NB when marginally higher pressure drops can be accepted.

The ND provides the same proven ring disc/radial guide design as NB and friction free guiding with aerodynamic flowpath through its two ring shaped flow ports, but with a long API 6D face to face dimension.

The Hybrid NZ valve combines the hollow ring disc of the N type with the single spring guidance of the Z Type making it ideal choice of valve for low flow gas applications.

The NC is the compact model of the centrally guided ring disc design. With its short face-to-face and reduced weight,the compact NC is a lower cost solution to the NZ when marginally higher pressure drops can be accepted.

With the NA the ring disc is centrally guided with a single spring. Utilising the same valve body as its sister valve the Type N, it provides the same internal flow profile and, consequently, the same minimal pressure loss as the Type N long API 6D Face-to Face dimensions
