Is it a wafer-type valve? L = thickness of 2 flanges + thickness of 2 gaskets + thickness of the blind plate + length of the valve + thickness of 2 nuts + 2 times the flange thickness tolerance + length allowance (usually 3–5 mm). Detailed information can be found in HG20634 or SH3404 – go and take a look
