Product Description

- Jewellok -

Is A Ultra High Purity (UHP) Gas And Chemical Delivery Systems Manufacturer And Supplier In China, Manufacturing Ultra High Purity Regulators, Ultra High Purity Diaphragm Valves, High Purity Regulators For Use With Specialty, Flammable, And Industrial Gas Flows With Compact Construction And High Flow Capacity.

 

Introduction
Jewellok DPR1 series valve is a compact high purity two-stage cylinder regulator with tied diaphragms for low flows of toxic, flammable and pyrophoric gases.Diffusion-resistant metal diaphragm seal ensures gas purity and integrity.
 

Features
*Maximum Inlet Pressure 3000 psig / 207 bar
*Outlet Pressure Ranges: 0-25psig, 0-50psig, 0-100psig and 0-150 psig 0-1.7bar, 0-3.4bar, 0-6.9bar and 0-10.3 bar
*Design Proof Pressure 150% maximum rated
*Leakage Internal: Bubble-tight External: Design to meet < 2 x 10-8 atm cc/sec He
*Operating Temperature -40°F to 140°F / -40°C to 60°C
*Flow Capacity Cv = 0.05
*Maximum Operating Torque 30 inch-lbs / 3.4 N.m
*Decaying Inlet Characteristic 0.06 change / 100 psig inlet, 0.004 change / 6.9 bar inlet
 

Advantages
*Excellent decaying inlet characteristic: 0.06/100 psig or 0.004/6.9 bar inlet changeP
*ositive seal designCaptured bonnet ports
*Both diaphragms are convoluted for greater accuracy and sensitivity
*Metal-to-metal diaphragm to body seal to minimize diffusion
*Diaphragm-to-valve link enhances seat sealing integrity
 

More Options
Optional outlet pressure ranges:0-25psi,0-50psi,0-100psi,0-150psi
 

Stainless Steel Low Pressure Seal Pneumatic Diaphragm Control Valve For For HP & UHP Gases

 

Remote Actuation UHP Diaphragm Valve with IoT-Compatible Position Monitoring

 

 

Ultra high purity regulators are designed to provide a maximum diffusion resistance of single stage two stage dual stage ultra high purity gas regulators.

Metal diaphragms and high-purity seats and seals minimize or eliminate out gassing and inboard diffusion.
