Choosing a process control valve for an industrial line means balancing actuation method, body material, connection size, and price. The Schrader Bellows Sinclair-Collins C064-4002 is listed at USD 664.70, and its specifications deserve a close look before you commit to a purchase.
Quick verdict
The C064-4002 is a focused option for a specific type of installation. If the specifications match your existing setup, it's a worthwhile candidate-but only if everything lines up with your requirements.
Who it suits
The valve suits buyers who already use air-based control in their process lines. Its pneumatic actuation means you'll supply air pressure to move the valve rather than using a manual handle or electric motor. The threaded mounting allows it to be installed into NPT-threaded pipe openings, and the bronze body offers corrosion resistance in many media.
What stands out
The new open-box condition is a key point-it means the valve is new, but the original packaging may not be intact. The product also carries the Schrader Bellows Sinclair-Collins model line with MPN C064-4002 for reference.
Meaningful trade-offs
The 1-inch NPT connection size means it will only fit pipes or fittings that match exactly; other diameters will need a different model.
Bottom line
The C064-4002 offers a clear set of specifications for a specific application. If pneumatic actuation and bronze construction are what your line requires, the USD 664.70 asking price puts it in a reasonable range.

At USD 664.70, this valve brings together a 1-inch NPT threaded connection, pneumatic actuation, and a bronze body in new open-box condition. The reason to choose it is that pairing of pneumatic control and bronze construction in a common NPT size-ideal for buyers who already have air supply and want corrosion resistance. The limitation is the open-box condition and the fixed thread size; if you need a sealed package or a different connection size, this specific valve won't fit.
