Processing Highlights

Sophisticated manufacturing processes utilized are supported by quality assurance procedures at every production step right from incoming steel to product packaging.
Materials:- The standard Precicomp valve plate and reed material is of AISI-420 stainless steel which provides uniform high hardness. Chemical compositions are shown as in table below.

Chemical Composition
AISI-420 SAE-51420	C-max	Mn-Max	P-Max	S-Max	Si-Max	Cr	Ni
	0.15	1.00	0.04	0.03	1.0	12/14	-	-

Spring Plate materials is AISI-304 stainless steel which is hardened and tempered steel. Chemical composition are shown as in table below.

Chemical Composition
AISI-304 SAE-30304	C-max	Mn-Max	P-Max	S-Max	Si-Max	Cr	Ni
	0.08	2.0	0.045	0.03	1.0	18/20	8/12	-

"LASER CUTTING " techniques developed with many years of research and "Edge Finishing" which is desired to remove blanking edge stresses on the surface of the valve without affecting surface flatness are achieved to improve fatigue strength to all edges of the flapper valve.

Finishing processes at each production step has to go through quality standards and each lot receives final checking by an inspector.

Unique anti-corrosion techniques are also an integral part of finishing process. Parts are cleaned and demagnetised then protected with special rust preventives to allow most of the customers to put these parts directly in to assembly operations.
