Overview

GF 314 series valves not only maintain the advantages of zero leakage, corrosion resistance, and no scaling of diaphragm valves, but also achieve flow capacity close to ball valves through the use of non weir/low weir and large diameter diaphragms. They are particularly suitable for corrosive or high-purity media applications that require high flow, low residue, and easy maintenance.

Product Details

Almost direct traffic characteristics
The diaphragm adopts a weir less or low weir design, and when fully opened, the medium passes almost straight through. The Cv value is more than twice that of traditional weir diaphragm valves, and the pressure drop is small, which can replace some ball valves/butterfly valves.
All plastic 'true union' structure
The two ends of the valve body are true union sockets, which can be interchanged with various materials such as PVC-U, CPVC, PP, and PVDF; During installation or maintenance, it can be removed as a whole without the need to disassemble the pipe
.
Boltless clamping design
The valve cover and valve body are locked with threaded pressure rings and positioning claws, eliminating the traditional four bolts to avoid leakage points caused by bolt corrosion and torque relaxation
.
Multiple diaphragm materials are available for selection
The liquid receiving diaphragm includes EPDM, FPM, PTFE/EPDM composite, PTFE/FPM composite, NBR, etc., which can meet different chemical compatibility and temperature requirements
.
High pressure level
Standard version 150 psi (10 bar), PVDF valve body optional 240 psi (16 bar), belongs to high pressure resistance level in plastic diaphragm valves
.
Zero static, evacuable version (Type 51)
The same series has derived a "zero static" structure, which uses the pipe wall as a sealing weir to achieve full emptying and no residual liquid, suitable for ultra pure processes such as pharmaceuticals and semiconductors
.
Flexible driving mode
Manual handwheel with visual position indication is standard configuration; It can also be equipped with pneumatic (PA/PA11/PA21) or electric (EA31/EA42) actuators to achieve remote control.
Wide size coverage
The nominal diameter of DN10 – DN50 (189-2 in) is within the conventional range of the 314 series; Larger diameters (DN65-DN100) are included in the 315-319 series, but have the same structural features.
