Supply pinch valves aluminum DN25-400, pinch valves, cast iron/steel/stainless steel, hose valves pneumoperitoneum, rubber nozzles to hose valves, diaphragm valves, cast iron/steel/stainless steel / rubber-lined, diaphragm valves pneumoperitoneum, gate valves/globe valves/ball valves lined with rubber from China at best prices.

The feature of hose valves:
1. Unobstructed full bore;
2. Low hydraulic resistance;
3. Without zavalivanija;
4. In the presence of the remaining particles still can be closed with zero leakage;
5. Without gap and dead places, which hinder operation of valves;
6. Low maintenance costs;
7. Simplicity in design, not subject to the harsh effects of the environment.

The hose gate valve is used in pipelines transporting products with high viscosity or a high content of abrasive particles. Classic shut-off valves in such conditions does not work because the abrasive slurry can damage even the most resistant shut-off element. Therefore, the pipelines transporting highly contaminated streams, using a special valve, shut-off element which is simply pinched the elastic insert in the seat of the body.
HOSE GATE VALVE — DESIGN FEATURES
Hose fittings, like any other, the locking element consists of the following parts:
Case
The locking node
Management bodies
Such a scheme does not depart from the classical layout of valves. However, the specifics of the design of valves of this type are evident in each node of the device. For example, the valve housing is formed in the form of a tee, the horizontal line which formed the backbone ends, and the vertical is fitting that accepts the valve. However, in the inner part of the valve body there is no saddle, receiving the locking element. The ends of the main reinforcement is designed in the form of threaded fittings (nipples) or flanges.
Hose valve fiancewas the locking element hose fittings different from those of the parts shut-off and control devices for pipelines dramatically. This node is decorated not as a body of rotation, and as the wedge – locking element hose fittings are made in the form of elastic, hollow cylinder (in fact a segment of hose), which is simply compressed by the wedge or piston.
Controls hose valve designed according to the classical scheme of the vertical end of the body inserted the threaded rod, the end of which is fixed the locking device. Design features of the management bodies are manifested in the form of locking device, which resembles a press. Moreover constipation can consist of two halves – top and bottom, which move towards each other, covering the elastic tube. It is on this principle operates valve hose 33а17р, constipation which consists of two parts.
