Material :

• 420 STAINLESS STEEL (SS)
• EN42J
• EN47
• 7C27MO2

Highlights :

• Applicable to R717(Ammonia), R744(CO2), HCFC and HFC.
• Also utilized in chemical and petrochemical applications.
• Quick and simple valve maintenance. It requires less effort to replace the top part and no welding is required.
• Designed to operate at very low differential pressure of 0.58 psi g(0.04bar).
• Modular Concept:
• Each valve body is available with a number of different sizes and connection types.
• Possible to transform/convert MSCA-S and MCHV into any other product of MSVL family (stop valve, regulating valve and strainer) by replacing the entire top part.
• Each Ammonia Stop valves type is clearly mentioned with type, size and operating range.
• Designed with an integrated damping chamber preventing valve flutter in case of low refrigerant velocity and/or low density.
• Quite easy to disassemble for inspection and maintenance.
• Damping facility provide protection against pulsation.
• Internal backseating enables the replacement of the packing gland (spindle seal) while MSCA valve is in working condition.
• Optimal flow characteristics ensure quick opening to the fully open condition.
• Valve body and bonnet material is low temperature steel as per PED norms.
• Maximum working pressure: - 754 psi g (52 bar g).
• Operating temperature range: - 60 to +150°C (– 76 to 302°F).

CREG is angle-way and straight-way regulating valves, which act as normal stop valves in the closed position. Regulating valves are designed to meet the strict quality requirements on refrigerating installations and are carefully designed to present favorable flow conditions and accurate linear characteristics CREG is equipped with internal back seating enabling the spindle seal to be replaced with the valve still under pressure.

Features :

• Applicable to all common non flammable refrigerants including R 717 and non corrosive gases/liquids dependent to sealing material compatibility.
• Designed to ensure perfect regulation.
• Internal backseating enables replacement of the spindle seal whilst the valve is active, i.e. under pressure.
• Easy to disassemble for inspection and possible repair.
• Max. operating pressure: CREG: 25 bar g (362 psig) Full temperature range packing gland - 46/+150°C.

Technical data Applicable for the refrigerants R717 (ammonia, Nh3), HFC, HCFC (e.g. R22, R134a, R404a) and other refrigerants dependent on sealing materials compatibility within a temperature range of -30°C/+100°C Flammable hydrocarbons are not recommended. 

Pressure setting range : 10-25 bar (145-363 psig) the valve is designed for strength test : 40 bar (580psig). Leakage safety: Same as set pressure. For further information please contact your local Castle Sales Distributor.

Important :

The CSRVA safety relief valve is dependent on the back pressure (if the back pressure is higher than the atmospheric pressure, the opening pressure will be higher than stated set pressure) Special circumstances such as vibrations (which should be avoided) and oscillating pressure may require an increased difference between the operational pressure and the closing pressure.

Pressure Setting :

The operating pressure of the plant should be at least 15% below the set pressure. This allows a perfect re-seating of the safety relief valve after having been activated. .

Temperature Range : -30/+100°C.
