An API gate valve refers to a gate valve that meets one or more specifications set forth by the API. The API (American Petroleum Institute) is a strong trade association that represents gas and oil producing companies across the United States. Among other things, the API develops standards and specifications for all things related to the petroleum industry, from pressure vessels, to values, to thread gauges.
API Standards
API Standards are meant to increase the safety, compliance and overall efficiency of it's members operations. Different API standards can specify almost every aspect of a gate valve from its size, to its flange type. API Standard 6D for example specifies the design, manufacturing, testing and documentation of ball, check, gate and plug valves used in pipelines
Gate Valve
A gate valve controls fluid passing through a valve by raising or lowering a square or round wedge into or out of the path of a fluid. When fully closed, the surface of the wedge meets a corresponding seat in the valve body preventing fluid from passing.
Rising Stem Gate Valve
In a rising stem gate valve, the wedge attaches to the valve stem. When the valve is operated, the stem rises and falls along with the wedge giving the operator a visual indication of the state of the valve.
Non-Rising Stem Gate Valve
In a non-rising stem gate valve the valve body captures the stem. Thus the valve stem gives no visual indication of the state of the valve. This valve would be used when vertical clearance is an issue.

Hydraulic Control Valves from PRC
Features and Maintenances of Hydraulic Control Valve
World Industry Valve Co.,Ltd. a professional industry valve wholesaler and valve supplier, has many years experience in manufacturing ball valve, gate valve, globe valve, check valve, plug valve, butterfly valve and pipe fittings in carbon steel, stainless steel.
The hydraulic control valve is the valve that controlled by hydraulic pressure. It is composed of a main valve and other attachments, such as pipeline, pilot valve, needle valve, Ball Valve and manometer. According to the use, function and different occasions, it could evolve into telecontrol float valve, reducing valve, slow shut Check Valves, flow control valve, release valve, hydraulic electric control valve and pump control valve, etc.
The hydraulic control valve should be installed strainer and facilitated to drainage.
The hydraulic control valve makes good use of smooth run water, so there is no need to add motor oil. If the main valve's spare parts are damaged, please do dismantling under the following instructions. usually the damaged ones consumed in the inner valve are mebranes and o-rings, the others are less.
1. First closing the Gate Valve forward and back of the main valve.
2. Loosing the tube union screw on the main bonnet to releasing the inner pressure.
3. Unsling all the screws include the essential copper pipe in the control pipeline.
4. Take bonnet and spring.
5. Lift down the central spindle, mebrane, piston, take care the membrane.
6. After taking away all of the above, examining whether the marine and o-ring are damaged. If not, please do not subdivide the inner spare parts by yourself.
7. If you find the mebrane or o-ring damaged, please loose the cap on the central spindle and resolve them gradually. After doing that, you may install the new mebrane and o-ring.
8. Exactly check whether the main valve's seat and central spindle are damaged and clean the sundries inside if there is.
9. Assembly the main valve's spare parts according to the opposite direction. Note without blocking.
