Company Name : Hale Hamilton

Description : N62 is a body ported, non-rising stem, balanced stop valve. It is ideal for use with non-oxidising and non-corrosive gases in high pressure applications (up to 500bar) where tight shut off is required. The pressure balanced spindle prevents the process pressure from loading the operating thread. This means that handwheel torque is low even at the maximum operating pressure of the valve. A visual/tactile indicator shows when the valve is open. Connection is via flanged adaptors which either have industry standard threaded ports or profiles suitable for brazing or welding to pipework. We can provide adaptors to special requirements on request. N62 is “Pi marked” and may be used a primary closure for transportable pressure vessels (e.g. cylinder banks on trailers).

  • Meets the requirements of BS EN ISO 10297:2006
