Installs uses and maintains
　The pressure releases the valve the valve body by the aluminum alloy compression casting forming, the spring attachment, the diaphragm capsule is composed, its contour is artistic, anti-corrosive does not have returns the rust, the semblance uses the static electricity to spurt spreads, paints adhesion, does not have flaking. The diaphragm capsule uses the 8K stainless steel manufacture, the diaphragm capsule joint meets on the valve seat the seal packing collar, the structure conforms to the standard.
