Asahi Type 21 Pvc Pvdf True Union Ball Valves U S Plastic Corp It blocks in two directions, upstream and downstream, leaving full pressure on the opposite end of the valve. true union design makes installation or repairs easier without expanding the pipe system. the built in spanner wrench on the handle is for valve disassembly and assembly. gray pvc or white pvdf body; fkm o rings; ptfe seats; full bore. Type 21 21a true union ball valve (1 2" – 6") type 21 21a ball valves are corrosion resistant plastic manual true union design quarter turn valves with hyperbolic flow characteristics, low pressure drops and reliable sealing. they are typically used in on off applications and are offer relatively poor flow control.
Asahi Type 21 Pvc Pvdf True Union Ball Valves U S Plastic Corp Plastic ball valves. these valves perform as an on off or modulating function. the ball valve name derived from the flow controlling ball valve located within the body of the valve. a hole through the center of the ball along one axis connects the inlet and outlet ports of the body. the ball itself is held in place by ptfe seats and rotates 90. Type 21 21a true union ball valve type 21 21a ball valves are corrosion resistant plastic manual true union design quarter turn valves with hyperbolic flow characteristics, low pressure drops and reliable sealing. they are typically used in on off applications. they are excellent for use in clean fluid service applicat. Type 21 21a ball valves are well suited for a wide variety of fluid flow applications. true union ball valves can be lifted from the line without having to move the piping simply by loosening the two union nuts. the valves can be disassembled, and parts may be replaced.they can be pneumatically or electrically actuated. ideal applications include:. Sample specification. all type 21 21a ball valves, sizes 1 2” to 4”, shall be of true union design with two way blocking capability. all o rings shall be epdm or fkm with ptfe seats. ptfe seats shall have elastomeric backing cushion of the same material as the valve seals. stem shall have double o rings and be of blowoutproof design.
