PPH Diaphragm Valve
PPH Diaphragm Valve is consists of a flexible disc that is sealed with a seat at the top of the valve body. It is excellent for use in restricted spaces.
Due to its widespread use in almost every industrial sector, a PP Diaphragm Valve is the most versatile of all valves. The main advantage is that only two parts, the valve body and the diaphragm, touch the active substance.
The “Minimum Dead Leg” valve type of PP diaphragm valve is well known in the industry. The diaphragm valves are excellent for flow control. By compressing the diaphragm against the weed. Our PP diaphragm valves are available with pneumatic or electric actuation.
This diaphragm sealing system makes PPH Diaphragm Valves & Pipe Fittings. For industrial and ecological engineering as well as manufacturing industries, the wide material range makes it excellent for hostile media, scratch media and highly viscous media.
It has many other uses of PPH Diaphragm Valves & Pipe Fittings. It can be used in the manufacture of drinking and ultra-pure water used in microelectronics and semiconductor manufacturing.

PPH Diaphragm Valve Technical Information
The CM is a manually operated diaphragm valve of reduced dimensions and particularly compact structure, ideal for use in confined spaces.
• Connection system for solvent weld and threaded joints
• Extremely compact construction
• Internal operating components in metal totally isolated from the con-
veyed fluid
• Valve stem in STAINLESS steel
• Compressor with floating diaphragm support
• Easy to replace diaphragm seal
• Corrosion-proof internal components
• CDSA (Circular Diaphragm Sealing Angle) system offering the following
advantages:
− uniform distribution of shutter pressure on the diaphragm seal
− reduction in the tightening torque of the crews fixing the actuator to
the valve body
− reduced mechanical stress on all valve components (actuator, body and
diaphragm)
− easy to clean valve interior
− low risk of the accumulation of eposits, contamination or damage to
the diaphragm due to crystallisation
− operating torque reduction

PRESSURE VARIATION ACCORDING TO TEMPERATURE
For water and non-hazardous fluids with regard to which the material is classified as CHEMICALLY RESIS-TANT. In other cases, a reduction of the nominal pressure PN is required(25 years with safety factor).
PRESSURE DROP GRAPH
KV 100 FLOW COEFFICIENT
The Kv 100 flow coefficient is the Q flow rate of litres per minute of water at a temperature of 20°C that will generate Δp= 1 bar pressure drop at a certain valve position. The Kv100 values shown in the table are calculated with the valve completely open.
