Manual or Pneumatically Actuated Forged Body 2-way valves with Access Port

Tandem access valves (like ported valves) provide access to the interior of the body at the lowest cross section when the body is oriented at the optimal drain angle. However, a secondary valve is included so that you can control the flow for sampling, steam sterilization, purging or condensate drainage. Final configuration detail is confirmed with you prior to fabrication.
