1. With two wrenches, firmly hold the BD2 Valve Seat (Screen Holder)

②

(See table above for

distance across flats) in place while slowly opening the BD2 Valve

①

(17 mm, ").

Be careful to avoid contact with fluid that will be discharged through the hole in the center of

the blowdown valve as the valve opens.

2. Close the BD2 Valve

①

and tighten to a torque of 30 N·m (22 lbf·ft), and confirm that there is

no leakage. If leakage continues, dirt or scale may prevent the valve from sealing. Open and

blow out again, then try to close once more.

Note: Do not leave the vicinity while the blowdown valve is in the open position.

CAUTION

• Always wear eye protection and heat-resistant gloves when operating the

blowdown valve. Failure to do so may result in burns or other injury.

• When operating the blowdown valve, stand to the side well clear of the

outlet to avoid contact with internal fluids that will be discharged. Operate the valve slowly and

surely, taking care to avoid the area from which internal fluids are discharged and any fluids

deflected off piping or the ground etc. Failure to do so may result in burns or other injury.

• Do not excessively loosen the BD2 valve when opening the blowdown valve. The valve stopper

pin installed to prevent the BD2 valve from being removed may break and internal pressure may

result in the BD2 valve being blown off, leading to injuries, damage and fluid discharge, causing

burns.
