SCOPE
370D6 ball valves 2” FP to 16” FP are full bore, through conduit, bi-directional, anti-blowout stem, double block
and bleed in closed and open position, with trunnion mounted ball for easy operation. These valves can be
equipped with plastic seat inserts made of RTFE, NYLON, or PEEK as the customer requires. All the seats are self-
relieve type seats to eliminate cavity pressure lock. All valves have a built-in sealant injection system for
emergency seat seal and also a stem sealant fitting for stem seal recovery. The valve uses backed self-lubricating
PTFE sleeve bearings and thrust washers for low torque operation.
The 370D6 valves are available in the sizes and classes as per Table 3.
Unless otherwise specified on the purchase order, all the small sizes of valves are equipped with a wrench head
(noted W in Table 3) as standard; all other valves are equipped with a gear operator (noted G in Table 3). The hand
wheel can be removed from the gear shaft by taking out the roll pin.
