Industrial Valve Manufacturers Since 1842

Hunt & Mitton Since 1842

Hunt & Mitton first developed their hazardous chemical valve range between 1948—1955 in cooperation with Imperial Chemical Industries in Birmingham UK. Since these early days Hunt & Mitton have maintained a presence in this sector of the valve industry. Today our products cover a wide range of chemical service applications. Our sizes range from DN15 (1/2”) to DN400 (16”) in a range of manual hand-wheel operated, or pneumatically / electrically actuated and fitted with solenoid valves for emergency shutdown. They include both the straight pattern for pipeline installation and angle pattern for vessel installation. Complimented by our Flowstream dedicated hazardous chemical control valve we offer a superb range of globe pattern isolation and control valves for critical and hazardous applications.

Bellows Seal Control Valves

Sizes 1” to 6” (DN25 to DN150)

Body Material cast –A352 LCC C Steel, A351 CF8M St Steel, A494 M35-1 NiCu, CW12MW NiCrMoW, CY40 NiCrFe.

End connections— Class 150, Class 300, PN40.

Our bellows seal control valve product combines the knowledge and know-how of hazardous chemical valves, designed for isolation and zero leakage to the environment, with control valves designed for modulating applications. This product has been designed with the safety features associated with the latest Euro Chlor GEST 06/318 in mind whilst maintaining the functionality of control valves such as longer stroke to provide a better flow modulation, smoother flow paths and a better pressure recovery factor compared to that of an ON/OFF globe valve. The body assembly has a wider chest to allow the use of more sophisticated trims such as multi-stage low noise for gases and anti-cavitation for liquid applications.

Applications

Severe services for hazardous chemicals including the following fluids:

Cl2 Chlorine – Liquid and Gas
HF Hydrogen Flouride Liquid & Gas
COCl2 Phosgene
AHCl Anhydrous Hydrogen Chloride
EDC Ethylene DiChloride
VCM Vinyl Chloride Monomer
NH3 Liquid Ammonia

Low Internal Volume Manual Bellows Seal Isolating Valves Series 8700/01 Globe Pattern

Polymerising Applications.
For applications which require low internal volumes of chemicals within the valve body and will be used on lower pressure applications, Hunt & Mitton’s low cost globe pattern fig 8700/01 isolating valve gives tight shut off and zero emissions outside of the pressure envelope.
Manufactured from the same high material content as others in the range and fully tested at 20 bar pressure, with the bellows unit guaranteed for 10,000 cycles by our team of engineers at the factory.

Sizes Forged 1 1/2” (DN40)
Body Material – Carb steel, stainless steel or CW12MW NiCrMoW, Nickel alloy.

Sizes Cast 2” to 8” (DN40 to DN200)
Body Material – A216 WCB, A352 LCC Carb Steel, A351 CF8M St Steel, A494 M35-1 NiCu Alloy, CW12MW NiCrMoW Alloy.
End connections—Class 150, 300, PN16, 25, 40.
