When the handle is perpendicular to the pipe, the valve is STANDARDSSee page double block AND bleed OPERATIONThe pressure-actuated seats and bleed fittings allow double block and bleed operation. When used for block andBleed, this feature permits the valve totake the place of two Valves . It also allows the operator to check up and downstream sealing by bleeding off the body BODY PRESSURE RELIEFS eats will internally relieve excess body TESTED FOR SAFETYWKM dynaseal 370D Valves are qualified under API standard 6FA and API 607 4th TRIM STANDARDAll WKM dynaseal 370D Trunnion ball Valves come standard to NACE MR0175/ ISO 15156 for Buried Service.

4 The End Entry ball Valve for gas, oil and product pipelines, it s the choice for gas distribution and other specialized dynaseal 370D4 Trunnion ball Valves offers all the required features and options demanded by the gas transmission, gas distribution and oilfield production industries. Seat and stem sealant injection fittings, low pressure sealability comply with ASME/ANSI , API 6D, API 6FA and API 607 4th Edition Standards. The End Connections may be specified in Flanged, Weld End or Weld by Flanged End AND BENEFITSPRESSURE-ACTUATED SEATSThis valve uses pressure-actuated seats with locked-in non-metallic face seals. To assure tight sealing at low pressures, special wave springs force the seats against the ball .

5 At higher pressures, the upstream seat is forced against the ball by the pressure working across the differential between the area of the seat insert and the seat higher the pressure, the tighter the SEAT SEALANT INJECTIONIn the event of damage to the valve seat, sealant can be injected to temporarily seal the valve until repair can be performed.(Optional in 2 in. - 4 in.
