Series 700 Pop Action Safety Valve

• All Metal-to-Metal Seating Surfaces – Trim specifically designed for high temperature service, plus enhanced chemical compatibility.
• Patented Flexible Disc – Reduces impact wear while increasing seat tightness.
• Dampened Trim – Dampening chambers control the opening and closing response, increasing valve cycle life.
• Non-Flowing Pilot – Reduces seat wear and minimizes entrance of dirt and particulates in the pilot.
• Adjustable Blowdown – Blowdown can be adjusted between 3% and 15% by turning the blowdown adjustment sleeve. Upper and lower blowdown rings and pins are not required, saving time, parts and costs.
• ASME Section VIII Code Stamp – Certified National Board capacities for steam and gas service assures user of independent third party flow rate verification.
• Unique Field Test Capability, this option allows accurate set pressure verification with valve in service. No system isolation block valve or rupture disc required.

• For maximum operating conditions, it is recommended to use dual pilots with built-in switching mechanism.
• The safety lock allows the operator to isolate only one pilot while the active pilot protects the system.
• In-service testing and replacement of pilot under operating condition with full system protection.
