Description

PHF-DD-HF series modulating pressure independent control valve (PICV) used for balacing the piping network which pipe size range from 32 to 200 mm in HVAC system. The PICV combines the functions of hydraulic balancing and modulating control in one unit. It controls the water flow and temperature automatically to save energy rationally and realize intelligent management by its intelligent module device. The PICV features with high control accuracy and strong antielectromagnetic interference capability, is especially suitable for the variable flow piping system with large load fluctuation.

Features

Good stability: Flow value is not influenced by pressure undulation and is not influenced by each other.
Energy-saving: It saves more 6-20% energy than traditional system.
High efficiency: Greatly shorten the debugging time and high efficiency running.
Higher temperature control precision, more comfortable than the traditional type.

Instruction
This series valve can be matched with Siemens actuator.
That valve stem downward running is the closing direction of the valve.
Make sure the pipe is clean and without oxide and metal after welding before installation.
It must be at the same point and free from shocks when connect the pipe and valve body. The flow direction should be same as the direction of the label.
When the actuator is vertically installed on the valve, please avoid installing it under the valve to leave enough space for daily maintenance(like remove the actuator).
Cut off the electricity to make sure there is no pressure in the water system when maintenance.
DFQ-HD Series Motorized Valve Actuator

DQF-H series motorized valve actuator is matched with 2/3-way motorized valve to adjust the medium flow.It’s widely used in central air conditioning system, heating system and other occasions to meet the user from simple single-room temperature control to complex building automatic control requirements. It can achieve the required ambient temperature,obtain a comfortable environment and save energy through flow control.
