Design

RAYS cast steel check valves are designed and manufactured to provide maximum service life and dependability. All check valves meet the design requirements of American Petroleum Institute standard API600 & 6D.BS EN 13709 and generally conform to American Society of Mechanical Engineers standard ASME B16.34. Valves are available in a complete range of body/cover materials and trims.

Ranges of Materials

Standard body/cover materials include nine grades of carbon, low alloy and stainless steels, for special applications they can be supplied in other grades of alloy and stainless steel, there’s a full range of trim materials to match any service optional packing and gasket materials are available for a full range of service conditions.

Available Modifications For RAYS Steel Valves

Trim changes
End connection modifications
Packing and gasket changes
Operator mounting
Handwheel extensions

Pressure equalizing
Customer specified coatings
Weld end bore changes
Oxygen & chlorine cleaning & packaging

Features and Application:

Bellows globe valve adopts sealed stucture.In common valves, the packing seal of the stem ages fast and it is easy to leak,but this design totally eliminates these short comings.Apart from increaseing the efficiency of materials and the safety of production equipment,it not only reduces maintenance the costs and frequent maintenance of products but also provides a clean and safe working environment. Double seal design(bellows and packings),if the bellows invalidates,the stem packings will prevent outside leaking. There are no fluid loss,but it reduces the energy loss and improves the equipment safety. Longer service life,less maintenace and lower operating costs. Firm and durable seal design of bellows ensures the zero leakage of stem and provides more reliable performance and no maintenance. Quenched stem and surface nitridation with good performance of corrosion and friction resistance. Excellent performance,graceful outline,and more visibleness with position indicating of stem.

A)Eyebolt For 150Lb-8″,300Lb-8″, 600Lb-6″,900Lb/1500Lb/ 2500Lb-4″ & over.	B)BC Bolted cover. welded cover and pressure seal bonnet in services requiring frequent cycling or with high pressure/temperature variations.	C)End Connections A choice of flanged, RTJ flanged or buttwelding end for piping flexibility.
D)Body-to-Cover Joint A male and female joint or tongue and groove joint is used 150Lb to 600Lb valves. Ring joint is used in the body to cover connection in 900Lb & higher rated valve.	E)Outside Lever And Weight All external hinge pin swing check valves 12″ and smaller are available with an optional outside lever and weight, internal hinge available with all swing check valves.	F)Seat Rings Separate heavy duty, full ported rings for easy maintenance. Screwed or welded connectioninto body.
G)HCU weighted mechanical accumulator This design can be used to either dampen or assist closing of the check valve disc depending on orientation. by using the hydraulic control unit to buffer action the disc, the valve opens at lower flow rates.
