Pasco - Diaphragm / Pinch Valves
Pinch valve is simple in construct. It is made of three parts, i.e. body, pipe sleeve and actuator. Its superior performance has far surpassed gate valve, plunger valve, ball valve. What’s more, it can be tested for a long time. Our company introduces European pinch valve manufacturing technology and the key pinch valve possesses a lot of characteristics, i.e. full bore, wear proof, anti-corrosive, clean, scale control ,unaffected by service flowing direction and no need for equipment and maintenance.
According to the different usage in the industrial field, our company uses different rubber material and manufacturing technology. Pipe sleeve can be suitable for different service, for instance: mud, coal, water containing a lot of quartz sand, sewage, scale water, acid, alkali, salt, oil, food and medicine. Its driving device can use manual, pneumatic, hydraulic or electric. Pinch valve is mainly used in the fields of sewage treatment, electric power industry, mine industry, metallurgy industry, chemical industry, pharmacy industry, paper industry and food industry.
Pinch valve’s main parts are pipe and sleeve. Pinch valve can be controlled by manual, pneumatic, hydraulic or electric. It possesses high restriction function. When valve is restricted or closed, its pipe and sleeve and the valve center line are in symmetry, so it can reduce pipe sleeve’s wearing and prolong valve service time.
When pinch valve is closed, its pipe sleeve and valve body have large contact surface. Our company’s pipe sleeve is elastic and has a long service time. It has no wearing after running millions of times. The pipe sleeve has two advantages: one is that it can endure the wearing of residue. The second is that the valve can also be closed tightly even though residues and particles are in the pipe sleeve.
- 100% full bore. Pipe sleeve adopts full bore design, which makes valve have no dead angle and seam, and deal with particles in the service staying in the seat or the bearing in order not to block valve running or make valve fail.
- Wearing proof, anti-corrosive. Pipe sleeve has complicated manufacturing process and uses different high strength fibers ameripol material. The product can be used in different purpose of industry. Its effective design makes it suitable for hard particles and all kinds of fluid, and it is wearing proof and anti-corrosive.
- Self cleaning function. Pipe sleeve adopts full bore soft rubber design, liner is smooth and it has no scale. And it has self cleaning function when open and close pinch valve.
- No need for equipment and maintenance. Pinch valve is simple in construct, and the pipe sleeve is the only contact parts with fluid, no packing material needed to maintain. So it makes valves not need to maintain and use expensive and special material. Besides, it has the minimum maintenance period and expenses.
- Superior control characteristics. Pinch valve can be regulated easily if you rotate the wrench to control the constant capacity. It can be controlled by pneumatic, hydraulic or electric.
- Simple construct. Pinch valve is made up of three parts: body, pipe sleeve and actuator. Valve`s general construct can make users choose body construct, sleeve material or actuator according to their own process.
The process of manufacturing pipe sleeve is very complicated. First, wind multi-layers of rubber material together. Then strengthen them with multilayers of nylon. These multi-layers of nylon are located in the middle of the pipe sleeve. The outside is attached with wearing proof surface. And then press and shape, so every layer will unit together.
Because of complicated manufacturing process, different ameripol rubber material, products made of these materials can be used in different purposes of industry. Besides, the elasticity and hardness of sleeve can be regulated at random.
