API Valve

Gate valve features:
1) Size: NPS2" - 18"
2) Pressure: class 150 - 1,500
3) Material: 2" -": WCB, LCB, WC6, WC9, C12, C5, CF8, CF3, CF3M, and CF8M
4) Design and manufacture standard:
thermal power type steam trap

1.Attached with steam or air heat preservation mechanism and uneffected by the environmental hunidity ;with operation frequency decreased and service life prolonged .
2.Provided with filter screen and drainage valve.
3.The valve runs flexibly and relibly with large displacement.
Working principle:
By taking advantage of themodynamics characteristics , secondary evaporation will arise when the
BELLOW TYPE STEAM TRAP

Structural characteristics:
1. Metal bellow elastic cells can be self-adjusted between 65 and 110,also can be manually adjusted under discharge temperature.
2. It can exhaust automatically without air binding .Fluctuation of pressure wont affect the normal operation of drain valve.
3. All the internal components of the valve are made of stainless steel,,with strong anticorrosion and long servic
lever ball float type steam trap

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 is 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 rotection.
4.At the beginning of ventilation, all the valves start and low-temperature co
free semi ball float type steam trap

Structural characteristics and working principle:
When the drain valve does not start, free semi ball float settles over the transmitting tube. When the drain valve is in the drainage state, the steam will be enter into the valve body through filter screen and transmitting tube. When the steam volume increases to certain degree, the steam ball float will float under the action of float force and
free ball float type steam trap

Structural characteristics:
1. It can drain successively with stable performance ,large displacement and low air leakage.
2. It can saturate water successively so as to have little condensate water of equipment,rapid heating up and stable heating temperature.
3. Automatic cold air exhaust mechanism with reliable operation ,but without air lock or noise.
Working principle:
The ball float ins
forged globe valve

Features: 1) Design and manufacture to ANSI, API or GB 2) Valve inspection and test to API 598 3) Structure characteristics B.B OS&Y, W.B OS&Y or P.T.OS&Y 4) Material to AISI/ASTM 5) Material of main body: A105, F5, F11, F22, 304, 304L, 316, 316L, LF2
check valve

Check valves are mechanical valves that permit gases and liquids to flow in only one direction, preventing process flow from reversing. They are classified as one-way directional valves. Fluid flow in the desired direction opens the valve, while backflow closes the valve. The mechanics of check valve operation are not complicated. Most check valves contain a ball that sits freely above the seat, w
API gate valve

Gate valve features: 1) Size: NPS 1/2" - 36" 2) Pressure: class 150 - 1,500 3) Material: a) 1/2" - 2": A105, LF2, F11, F22, F5, F304, F316, F304L, and F316L b) 2" - 36": WCB, LCB, WC6, WC9, C12, C5, CF8, CF3, CF3M, and CF8M 4) Design and manufacture standard: API 600, BS 1414, and ASME B16.34 5) Face to face standard: API 6D, ASME B16.10, DIN 3202, and BS2080 6) End connection standard: ASME B16.1
