The Western Valve DAN-EX is an accepted Block and Bleed Valve (DBBV) as it has two independent seating slips that are mechanically expanded against the body seat by the downward movement of the tapered plug. The seating slips will seal with both high and low pressure imposed on both upstream and downstream sides of the valve. With the product now trapped in the center cavity between the two independent slips and the body bleed valve can be opened to verify 100% positive shutoff at high or low pressure.

(661) 327-7660 REQUEST PRICING DAN-EX VALVE APPLICATIONS AFTERMARKET ABOUT CONTACT Double Isolation & Bleed Valve DAN-EX Is Made For Double Isolation & Bleed The DAN-EX dual expanding plug valve has two independent slips that are mechanically expanded against the body seat and will not relieve pressure to the downstream or upstream side. The Western Valve DAN-EX does not rely on pressure or springs to seal. Any fluid trapped in the center body cavity (between both slips) of a closed DAN-EX will be subject to a rise in pressure due to thermal expansion because the valve does and will not leak upstream or downstream. This pressure is relieved by a differential thermal system (DTR) and piped to the upstream side of the valve. The Western Valve DAN-EX meets both DB&B as well as Double Isolation and Bleed applications.
