Resilient seated gate valves are the perfect solution as a closing device in pipeline systems. Be suitable in applications with water supply, sewage treatment and neutral liquids in the mining industry, enterprises and high buildings.
We design and manufacture BS5163, DIN3352, AWWA C515/509, SABS664, AS2638, JIS B2062, socket end resilient seated gate valve etc.
Here we are introduce one type of our DIN3352 gate valve
Grey cast iron/ductile iron + fusion bonded epoxy coating
Grey cast iron/ductile iron + NBR/EPDM/FPM

Q:Which brand of electric valve is good?
Electric valve does not need to use imported, domestic boutique can meet.
Q:What are the production equipment in valve shop?
Gold processing equipment, such as cars, milling, drilling, grinding, slotting machines with little,Special equipment, welding machine, test press, grinding machine, painting line, shot blasting machineAuxiliary equipment, air compressor, grinder,
Q:The valve is rusty and can not be opened. What shall I do?
Remove the handle and lever the stem rotation with a wrench,
Q:What are the definitions of internal, external and leakage valves?
Outside leakage generally refers to the valve and connecting flange or threaded connection between the seal and guide...
Q:Signal butterfly valve installation or other valve installation
The blue one is the separate body, and the red one is the welded flange on the pipe. There is rubber on the valve body, and it can be sealed with flange. This is determined by the structure of the butterfly valve, usually DN150 of the small diameter butterfly valve are installed this way. It comes with flanges, but the prices are much higher. Small caliber general butterfly valve is generally used for low pressure, leakage requirements are not high, so rarely use its own flange. With flanges, it is generally used in petrochemical systems and has a much higher pressure level.
Q:How does the valve open?
The general water switch valve and valve is counterclockwise, but there are some special components are clockwise off, specific can correct the switch travel around open to see, do not be too fierce force damage to the switch, you can switch with a wrench
Q:What does the RF of the valve mean?
The valve sealing surface in the form and code summary: sealing surface - RF - plane surface process FF ring joint face - RJ - TG groove convex surface - MFM applies to the following: PL flat plate flange hubbed welding neck flange with SO WN IF socket SW screw flange butt welding Th ring loose PJ/SE welding-on collar loose PJ/RJ flange cover BL lining flange cover BL (S) American Standard hubbed SO American Standard wn WN
Q:What's the valve as a unit?
Generally used as a unit of measurement
Q:What's the difference between a valve and a valve?
The correct unit should be called "group". A set of threaded valves include valves, live connections, and short tubes. A set of flanged valves consist of a pair of flanges (including bolts, gaskets, rubber pads), and short tubes".
Q:Is there any difference between the valve and the water valve?
Oil valve with water valve is that the oil valve is over the oil, and the valve is over water, the type of fluid is not the same.Valve (Famen) is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure.Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications. Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316), chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..
