What is the basic structure of a gate valve? Introduction As an important type of valve, gate valves are widely used in various fluid pipeline systems. Their internal structures can be classified into multiple types based on different classification criteria. The following will detail the classification of the internal structure of gate valves and their […]
Maintenance of pressure relief valves Introduction Safety release valves and valves used in critical operating conditions are essential for maintaining safe and effective systems and environmental protection. These valves are often used to control the pressure of the system and to avoid pressure buildup resulting in serious safety problems and hazards. This is why these
What is a Ball Valve? Introduction A ball valve is a valve with a circular channel of the ball as the opening and closing parts, the ball with the stem rotation to achieve the opening and closing action. The opening and closing member of the ball valve is a perforated sphere, rotating around the axis
Ball Valve Leaking? Top Causes and How to Fix Them Introduction During the use or installation of ball valves, internal leakage may occur. Due to frequent opening and closing or not being installed as required, the ball valve does not work properly. Here, we will explain the causes and treatment of ball valve leaks, as
Part I: General Introduction The remote control float valve consists of a main valve and its attached conduit, pilot valve, needle valve, ball valve and pressure gauge. When the pipeline supplies water from the water inlet, since the needle valve, ball valve and float valve are normally open, water enters the pool through the micro
Part One Introduction The lug type butterfly valve is mainly composed of a valve body, a valve bonnet, a valve stem, a plate, a sealing ring, etc. When the plate rotates around the axis in the valve body, the sealing ring will stick tightly to the plate, thereby realizing the opening and closing of the
Part I Introduction The wafer type dual plate check valve has a very simple structure. Compared with other check valves, its structure length is also very short, and the connection method is a wafer type. The valve plate is two semicircular butterfly plates, which are connected by a valve stem and forced to reset by
Part I Introduction Pipe Repair Clamp is a connector and repairer developed for pipeline connection sealing system, using stainless steel shell and rubber combination of compression sealing technology, suitable for 21mm-2032mm pipe diameter pipe connection. The product development concept breaks through the traditional pipeline connection technology, according to the requirements of different pipeline systems to
Part I: General Introduction Y-type filter is a commonly used filtering device in pipeline systems. It is called “Y-type” because of its Y-shaped appearance. The structure of this filter usually includes a cavity with a filter screen. The fluid enters from the inlet, and after being filtered by the filter screen, the impurities are intercepted
Part I: General Introduction The 500X pressure relief valve consists of a main valve, a pilot valve, a needle valve, a ball valve and a pressure gauge. It is hydraulically automatically operated and can be used as a pressure relief valve and a pressure maintaining valve. When used as a pressure relief valve, the water
Part I: General Introduction 200X pressure reducing valve is an intelligent valve that uses the energy of the medium to adjust and control the pressure. 200X pressure reducing valve is used for domestic water supply, fire water supply and other industrial water supply systems. The outlet pressure of the main valve can be adjusted by
Part I: General Introduction The bottom of the DIN F4 soft seal gate valve adopts the same flat bottom design as the water pipe, which is not easy to cause debris accumulation and allows the fluid to flow unimpeded. DIN F4 ductile iron elastic seated gate valve has significant advantages such as light switch, reliable sealing, good
Part I: General Introduction LANHUI Ductile Iron Handle Wafer Butterfly Valve has compact structure, easy 90°switching, reliable sealing and long service life, and is widely used in water supply and drainage of water plants, power plants, steel mills, papermaking, chemical industry, catering and other systems as regulating and shut-off use. The valve has a two-way
Part I: General Introduction The valve body is made of high-grade ductile iron, the weight is reduced by about 20%~30% compared with the traditional gate valve, easy to install and maintain. The valve flap adopts high quality rubber for the whole internal and external rubber coating, Europe’s first-class rubber vulcanisation technology makes the valve after
