Water control valve types and working principle

Hydraulic control valve is a water pressure control valve, which consists of a main valve and attached to the catheter ﹑ pilot valve ﹑ ﹑ ball valve and pressure gauge and other components. Hydraulic control valve types: According to the purpose of use, function and place can be evolved into a remote control float valve slow closing check valve flow control valve pressure relief valve hydraulic control valve water pump control valve. According to the structure can be divided into two types of diaphragm and piston valve. Hydraulic control valve diaphragm type and piston type two types of valves work the same principle, are based on the upstream and downstream pressure difference △ P as the power by the pilot control, so that the diaphragm (piston) hydraulic differential operation, fully automatic adjustment by water conservancy, So that the main valve disc fully open or completely closed or in regulation. When the pressure water entering the control chamber above the diaphragm (piston) is vented to the atmosphere or downstream low pressure zone, the pressure acting on the bottom of the valve disk and under the diaphragm is greater than the pressure above, pushing the main valve disk fully open (Piston) above the control chamber pressure water rotor pump can not be discharged to the atmosphere or the downstream low-pressure zone, the pressure acting on the diaphragm (piston) is greater than the pressure value below, so the main valve When the pressure value in the control chamber above the diaphragm (piston) is between the inlet pressure and the outlet pressure, the main valve disc is in the regulated state and the adjustment position depends on the needle valve in the catheter system and Adjustable pilot valve joint control. Adjustable pilot valve through the downstream outlet pressure and with its changes to open or close its own small valve port, thereby changing the diaphragm (piston) above the control room pressure value, control valve plate valve position adjustment.

PCR Tubes

What Are PCR Tubes?

PCR tubes are small tubes made of high-quality virgin polypropylene with a conical bottom. They have uniform thin walls to facilitate efficient heat transfer to the sample. These tubes are autoclavable and work well with most thermal cyclers.

What Are the Applications of PCR Tubes?

The most common application of PCR tubes includes various molecular biology biochemistry experiments requiring real-time PCR (Polymerase Chain Reaction). As these tubes have ultra-thin walls, they are perfect for accurate and steady thermal transfer in an array of thermocyclers. Our thin-wall PCR tubes meet the protocols required for PCR, qPCR, reverse transcriptions, and a variety of other applications.
