The effects of temperature/pressure on diaphragms and on linings in valve bodies should be considered in the selection process. The tensile properties of all materials decrease as the temperature increases. This reduction in strength can be compensated for by reducing the allowable operating pressure as fluid temperature increases.

The chemical activity of the fluid also increases as temperatures rise. This may be a consideration for choosing materials that are more corrosion-resistant.

TTI WARRANTY

This TTI product is made of the finest available suitable materials and every possible precaution has been taken to assure premium workmanship consistent with established quality control. Valves or parts which are proved faulty due to defective materials or poor workmanship will be replaced free of charge, F.O.B. our plant upon presentation of such proof. This warranty shall not cover the cost of installation and is valid for a period of one year from date of shipment. Specifications are subject to change; certified drawings are available upon request.

FLOW VS. VELOCITY
When selecting diaphragm valves, fluid velocity is a very important design consideration. Velocity through the valve should be limited to 15-20 ft/sec for clean fluids and 8-12 ft/sec for slurries.
