This reducing valve is the new type pilot extra-huge membrane pressure reducing valve developed by our company. It is greatly improved on basis of normal pressure reducing valve. The membrane use new material, enlarging the working area, so the slight change of upper pressure or lower pressure can be fed back to membrane of main valve, and adjust the opening of main valve to ensure the constant pressure of lower stream pressure.

Characteristics of api trunnion mounted ball valve
1. Design and manufacture of ptoduct according to american state standard ansi b16.34, american petroleum institute standard api608 api6d.
2. Liquid resistance smallest of all type of valve.
3. Open quickly, only turn on 90 degree may finilsh open and close.
4. Seat material use teflon or r-teflon, low friction, seal reliable open and close lightly.
5. Movement of ball on the middle of valve seat has wipe function so may suit medium of suspending granule.
6. Stem use back seal and hyperbatic structre which may prevent medium to striking stem on the condition of pressure.
7. According to the need of consumer, may design for anti-static electricity, fireproop and use a locker to prevent wrong operator.
8. Body of ball can be floated or fixed accordance with the of strength of opening and closing. Seat of fixed ball valve floatablerealize seal purpose depend on piston effect of medium pressure so to lighten the strength of open and close.

Structural characteristic
1.The valve adopts two kinds of sealing, e, g, balance double valve seat and single valve seat with reliable closedown and long life.
2.There's always condensate water available in front of the valve with reliable water sealing and non-leakage of steam.
3.No noise before operation in favor of environmental protection.
4.At the beginning of ventilation, all the valves start and lowtemperature condensate water and air are rapidly expelled to greatly shorten the start time for equipment.
5.Internal component is made of stainless steel, corrosion and cavitation erosion proof.
900 series din standard safety valve are mainly applied to the industries such as petroleum & natural gas, chemistry, electric, metallurgy & burning gas. Din safety valve, pressure safety valve, safety relief valve.
900 din spring loaded pressure safety valve
Din standard safety valve features:
Safety valves were first used on steam boilers during the industrial revolution. Early boilers without them were prone to accidental explosion.
Safety valves also evolved to protect equipment such as pressure vessel (fired or not) and heat exchangers. Safety valve term should be limited to compressible fluid application (gas, vapor, steam).
The two general types of protection encountered in industry are thermal protection and flow protection.
For liquid-packed vessels, thermal relief valves are generally characterized by the relatively small size of the safety valve necessary to provide protection from excess pressure caused by thermal expansion. In this case a small valve is adequate because most liquids are nearly incompressible, and so a relatively small amount of fluid discharged through the relief valve will produce a substantial reduction in pressure.

Laminated glass is a composite glass product composed of two or more pieces of glass which are bonded firmly with transparent adhesive. Laminated glass is characterized by excellent shock resistance and penetration resistance. Generally speaking, when it is shocked and broken, it will not be penetrated by the external impactors, and the splinters will not fly away from the interlayer, and thus it can provide security. The commonly used interlayer films of laminated glass include PVB, SGP, EVA and PU.
Glass substrate, which may be float glass, tempered glass, antisolar glass, solar control glass, coated glass (LOW-E) patterned glass or self-cleaning glass, and a variety of colored adhesive interlayer film (PVB) compose of beautiful and multifunction flat or bent laminated glass. With the properties of excellent light control, heat insulation, acoustic insulation, noise reduction, ballistic protection, burglar prevention and resistance to static pressure, our products can be widely applied to curtain walls, balusters, doors, windows, shower bathrooms, awnings, daylighting roofs, staircases, counters, interior decoration, hotels, banks, airports, furniture, military facilities and other industries and fields.
Product Varieties:
Our Company deals with the production of the following laminated glass series: common laminated glass, tempered laminated glass, hot bent laminated glass, antisolar laminated glass, SGP laminated glass, colored laminated glass, silvered mirror laminated glass, patterned laminated glass, decorative painting embedded laminated glass, coated laminated glass (LOW-E), self-cleaning laminated glass, sound control laminated glass, fire-proof laminated glass, security laminated glass, armored laminated glass, privacy laminated glass and electromagnetic shielding laminated glass, etc.
Features:
Laminated glass is characterized by transparency, superior mechanical strength, heat resistance, moisture resistance and cold resistance. Compared with common glass, it has superior performance in safety, security, noise insulation and radiation resistance.
