A diaphragm style backpressure valve creates constant back pressure. A PTFE or PTFE-
faced diaphragm offers maximum chemical protection and service life, and seals spring
and bonnet from product.

Be sure to install with fluid flow in direction of arrow on valve body.

Pulsation Dampener

A pulsation dampener is a pneumatically charged diaphragm-type chamber that
intermittently stores hydraulic energy. Used on the inlet, it can improve NPSHA (Net
Positive Suction Head Available) characteristics of the suction piping system. On the
discharge line it will reduce discharge pressure peaks and pulsating flow variations.
