 2-Way & 3-Way, Angle and In-Line Designs for Corrosive Chemicals, Water and Ultra-Pure Liquids

 

One valve design serves many functions...


• Preventing overpressure conditions in vessels and piping systems (relief valve).

• Providing by-pass flow relief to avoid pumping problems such as deadheading (pump bypass valve).

• Maintain backpressure in a piping system (backpressure regulator).

• Enhance pump performance by maintaining backpressure on the pump outlet (pump backpressure valve).

• Prevent gravity-induced siphoning through a pump, opening only when the pump is on (anti-siphon valve).

• NEW! Series TRVDT 3-port design...the features of our state-approved RVDT now in a 3-way valve!


One valve design provides many outstanding features...


• Offer wide range of pressure settings with sensitive operation.

• Provide smooth operation with higher flow.

• Fail-Dry safety feature (not available on RVD or RVTX).

• Each valve is individually tested prior to shipment.

• No wetted metals; all external fasteners are stainless steel.

• Maintenance-free designs.

• Designs for crystallizing liquids.

• Designs with no wetted elastomers for ultra-pure chemicals and water. Non-contaminating PTFE diaphragm
  designs.

• Factory pre-set if requested.

• Tamper-proof option.
